Quick question
What material is the TTE exhaust made from, stainless or mild steel
Cheers Rob
Stainless. (they would've dissolved years ago if not...) Heavy, & not as well-constructed as most would have believed.
With their longevity they must be stainless steel at least the outside, I have read that the internals break up, whether due to corrosion (of mild steel) or heat fatigue I know not.
The reason I ask is, looking at some pics of one on fleebay, areas look as rusty as fook, you would associate that with mild steel not stainless, also some of the welds look poor, anyone got a magnet to try one

There is a thread on maintenance subforum with photos of the internals :o

You will know/ see that there are various types of "stainless" steel each have their place but as with most things cost is an important factor.
The discolouration/ rust effect on your exhaust can be a mix of tempering colour, that is the colour a metal goes when heated to specific temperatures. In this case Yellow at 700deg F and Brown at 735deg F, as car exhausts are at around 500- 700 deg F this could be the case. Further contaminates on the exhaust surface will hold airborne crud particles which are baked onto the yellow/ brown tempered surface.
The areas of "rust" on your exhaust are likely the hot spots.
You will likely find that the "corrosion" you can see can be removed with a Scochbrite pad or similar.
@Joesson I am aware of the various types of stainless steel, we work with them all the time, there is a big difference between penetration of the protective "oxidation layer" and pure rust, if you look at the cropped image, that looks very much like carbon steel rust to me, hence I asked the original question

I agree that flange isn't stainless. The rest of it might well be.....

I had to have a replacement flange welded onto mine.
I wouldn't necessarily rely on the magnet test nowadays either, there's a lot of Chinese "stainless" that'll pass the magnet test but it's very poor quality, barely classes as stainless.

Indeed, I should've been more explicit that I was meaning in general terms. However it's not the first TTE to be found/sold in that general condition and they usually clean up well with some elbow grease and tin foil.
Admittedly the flanges look like they've been replaced at some point and the heat from welding can alter the properties of stainless as well.
All depends on price against age I suppose, as you've already mentioned the inners don't seem to outlast the shells anyway.

About it being the dogs dangles, well, I am relaitvely new to the MR2 and exhausts is one of my pet peeves so looked into that even befóre I bought one.
I found that yes it was a hallowed sales argument and it does look very good. It was immediately clear to me though that it does not flow any better, to not state worse, than OEM.
I can understand what TTE did with it. Toyota dropped the ball with the sound. So the TTE pot seeks to add looks with a better sound while still passing TüV homologation.
The disappointment from my pov is the ..... euhmmm.... odd construction of the interior.
That observed, it doés do what it is supposed to do; look and sound better.
Though not as rock solid as the OEM muffler, the quality is above average after market. Do be aware that all you see are quite old.
Lastly the TTE badge does have perceived value. It ís a sales argument. Same thing the TRD tag on other products while in itself that is no guarantee whatsoever.

My initial question was askesd based on some I have seen looking rusty in parts, and I mean rust, not surface contamination of stainless steel
You are correct as far as a selling point, most folk would go for TTE as its percieved to be a "factory option", I can understand that and yes if I could find a real good one at the right price I'd probably go for it, thats not to say I wouldnt look at others
A lot of the time we all fall into the trap of a name says everything, not always the case in my experience, especially comeing from a motorbike backgroud
Anyway, its all good banter

Quote from: Zxrob on October 30, 2019, 10:49A lot of the time we all fall into the trap of a name says everything,
Well, ´trap´ is a perception not necessarily correct as brand doés have value.
Take a Rolex.
Very good quality watch but there are comparable quality mechanical offerings at consíderably less. At the moment of reselling though the way more value for money one has a higher cost of ownership.
That is not mentioning modern technology because there are a 100 times more accurate wristwatches for peanuts yet a ´Róóólex´ on the wrist has a image value and a way better Casio F91-W does not.
Trap? Even though I am an avid F91-W fan, I don´t think so. Brand value ís real.
That is the brand added value versus product quality/functionality.
A TTE usually polishing up nicely is an example as well imo.
And then there is táste. Even definitely ´ricer´ stuff can be perceived as fun, thus bé fun ;-)
With hindsight one could make a case for the TTE pot being ricer (tongue in cheek - waiting for my tsurikawa ring - bwahahahaha....).
The TTE might not look good, but it sure sounds good to my ears! I'm not experienced enough in such things to assess the relative quality of it ... sometimes ignorance *is* bliss!
Mine came with my car. If I was shopping around for a new one, I might feel differently because the 2nd hand price of them seems a fair whack vs other potentially more well built options.

The ´best´ choice depending on what you are looking for.

I think this is true for many things. Manufacturers and service providers will work well and hard to produce a good product in order to obtain a name for themselves. Unfortunately once gained, some will rely on that name (and the fanboyism that goes with it) to sell and start to cut costs and corners. I'm not saying TTE have done that here but it's a pretty common modus operandi.
I do love the sound of the TTE. it's quite unique.
You don't hear many 4-potters that sound like an MR2 with a TTE exhaust.
You do pay a price. It's heavy, flow is suboptimal and frankly the insides look like the work of a plumber, not an exhaust manufacturer. But, it kinda works.
It gives the MR2 that fruity burble without massive penalties on a stock car. Unfortunately once you start to uprate performance, it has to go.
I bought mine for 220 about 3 years ago I think, which was a decent price. Not too much. Not too little. And it was in very good nick. I wouldn't pay much more than that though, even then. Especially that I now know the technical details of it, I'd be hard-pushed to spend 220. I'd rather spend more and go custom.

But if you'd never seen the inside of one you'd still have the original opinion, much like sosiges, I likes a good sosig but not many people want to see them being made...
And I'd be the first to agree you can't beat the burble from a standard car with a TTE, especially going steadily though a little village or between dry stone walls. Beats mine, Mike K's and even Tomaky's porker with the valves open.

Trouble is you can never get a decent recording that accurately portrays the sound, not without proper equipment.

I am just about elderly; qualify for age discount cards.
My gfs are thus in the same ´granny´ category. One even ís a grandma!
Both are what you would call respectable, the grandma even posh.
They don´t like making waves, they don´t like noise. They will both lóve the sound of mine. Were dissapointed when I reverted to OEM for MoT; said it was no longer sexy.
The previous gf is bordering religious fanatic and totally embarrased by anything drawing attention. She lóved ripping through the night though. It turned her on even!
Anyone tried or considering the Malian TTE copy?

It is actually a bit more complicated than that but that is off topic, heck; off forum :-)
And no, my ears are fine, they are réally lovely, loving company
On topic again; in retrospect I would not have messed with fabricating my own but fitted the Malian single pipe one. That is straight through with enough volume for proper absorbtion/expansion damping without slowing down at the perforated surfaces thus not narrowing the effective flow diameter.
It must be noted though that I live ´remote´ without conventional obligations so can choose when I go where.
I have not needed to be socially sensitive to close neighbours since mid eighties and have gone further off the reservation ever since.
If I would still be living in suburbia in The Netherlands, I would have the OEM cat with the above mentioned Malian. That is regardless of potential complaints; simply social awareness.
An observation about the latter. Things have changes incredibly. When I started with driving lessons, it was possible to get a practice zone assigned for your motorcycle. In my case it was half a large city. Helmets only just had become obligatory and my bike (Norton 500) had a 2-1 exhaust with undamped megaphone. Nobody even thoúght about complaining.
I live next door to a biker, older than me, with a Harley Fat Boy and an old Triumph. We get along just fine 😂

Sadly the same can't be said for their cat pipes, which is what makes me question their backbox. It's a very attractive prospect; cheap exhaust custom to MR2. But I'm watching it from a distance for now to see how they fair over some time.
As for the TTE - @CalltheMidlife is right; If I hadn't known about the internals I would never really have doubted the quality. But, the weight and known flow restriction has always been something in the back of my mind. Especially after spending a small fortune on a custom manifold and cat aimed at less restriction. It's then a bit of a constant nagging thought that the TTE is strangling potential created by the other things I've done.
Unlikely, I'm sure, as I'm still just stock :)

I take it no one on the site is running one, I've also been looking at the Cobra one too
Rob
I'm fairly sure there's a few folk on here running different versions of the Malian cat backs, just probably not following this thread to see the question.
I'm also reasonably sure that they're just rebranded imports, not that there's anything necessarily wrong with that, the Hamish manifolds are imports too but have been established a bit longer.

Most of the Swiss watch industry is rebranded Chinese import with 15 - 25% added value (timing and qc in the Swiss premises would take care of that) warranting the´Swiss Made´.
There seem to be a fair few owners on that Facebook group. TBH I'm pondering it as the consensus on the other thread seemed to be it was a bad idea to start butchering my TTE in case someone else wants it as-is.

The fúnctionally best would be sell it and enjoy the resale value to aid buying a better flowing one. Most will be more silent than a flushed TTE too.
There have been issues with the Malian ones not lining up very well with standard cats in the past but Lewis, who's selling them, is confident the latest lot are a better fit seemingly.
Still no long term reviews obviously but folk seem generally happy enough with the product and the sound.

Does it have any other performance mods or just TTE exhaust? What did you take the sound with, smartphone or voice recorder or gopro? And where did you put the microphone/gopro, on rear bumper?
I tried to record my car's sound last year, but my bloody Windows Phone didn't recognize specialised microphone as microphone, but as earphones instead (it refuses to recognize any mic as anything but as earphones) and thus didn't record any sound. :(

I'm sure there are hangers available on fleabay that would bolt straight on? Durability wise, if it only lasts 5 years you'll probably break even anyway on any repairs you might do to the TTE instead, I think you've already made your decision haven't you?😃

Subject to the TTE coming off unscathed when the car is SORN'd, (and selling!) I think so

Came to this thread a bit late. I had to have my TTE exhaust removed and opened up by Rogue Motorsport last June to identify & cure a nasty rattle from within the silencer. Here are the photo's of the interior. The pipes which pass through the silencer are surrounded by a wire wool material and the remaining space is then packed with fibreglass 'insulation' type material which is in 3" squares.
We identified that the welds holding the pipes which exit the exhaust inside the silencer had come loose and caused the rattle. These were welded back so are now solid. The fibreglass material was removed from the silencer, so its only the 'wire wool' which is doing any sound deadening. The outside of the silencer was welded back on and the whole system fitted back to the car.
What a result... no more rattle and the sound from the exhaust is far superior to what it was before, even though I was happy enough as it was ;) It's now a bit louder & just about right in my opinion, with a fantastic tone & sound.

The box they attach to though. That's another matter.
@mr2noob It WAS a dealer's option, right?
most certainly was

The bends and transitions are bad enough, but that T-joint tops it.

Taking the above on board.
Rather than starting from scratch. Is it reasonable, a competent zorst fabricator should be able to open up the box, re-design the plumbing for better effeiency and re-seal?
I say this simply because I really like the twin exit and TTE tips.
Quote from: mr2noob on November 2, 2019, 23:50I'm pretty much limited to TTE (unless I want to bother with homologations and sheet) since it was a dealer's option and thus OEM. It WAS a dealer's option, right?
I swap back to OEM before MoT.
Also, because the exhaust is totally hidden from sight, there is not going to me an issue as long as it sounds not too loud.
Most TTEs áre an issue here as the over time increased sound raises eyebrows and owners need to produce the dealer option info.

Yes, that is possible but modifying an exhaust is grounds for rejection.
You´d be better off with the Malian twin tip. That does not look molested and does not attract attention on grounds of sound whereas the TTE might.
If you want to be OCD then engrave or stamp the OEM homologation number in the Malian pot.
In retrospect I would have gone Malian single exit and do the MoT swap.

To the point:
Yes; just needs to cut the T-joint out.
Re-wrap the perforated pipes ofcourse when it is open.
Anyone used powerflow exhuasts for some custom work?
To lighten up the mood if needed:
Am at the coast with Málaga love. She is getting ready for us to have lunch at the beach; in a playful mood jumping rope with an electric cord in the nude.
She stops when she sees the dissected TTE entrails. Shocked. She is a totally a-technical person but thát she gets.
Her antics interrupted she stepped on the cord; now her ladyshave does not work anymore.
I blame the TTE for that ofcourse; if it where better she would have continued the show ánd shaved...
problem solved

I think that would be it. I had 2 pages but missing one you have found. Result.
Quote from: mr2noob on November 3, 2019, 16:11Btw., if I remember correctly, TTE is louder than Fox, right?
When as new it should not be.

I thought Fox were quieter? And from what I see they come with ABE so don't even need to be written in car's papers.
They conform to the same norm as the TTE so they should be as quiet. May very well be that the Fox ones are of better internal construction and unlike the TTE do not get louder over time.

I have a Fox fitted to mine and prior to the rest of my mods it was no louder than the TTEs I've been out with, the TTE on a standard setup isn't necessarily loud anyway just very distinctive and burbles nicely.

It's so ugly it's beautiful. I would much rather have this than KTM Crossbow.
We had that on the ROC stand at JAE the year before TTE launched their turbo kit

Spot on.
@mr2noob Just in case it gives some more leaverage.
I think with the links to the homologation docs and TTE brochure yesterday, it probably makes sense for me to stick with the TTE. I keep giving the Malian some thought (especially as eBay is running 10% off) but I've got some misgivings based on Facebook postings and how loud it could be.
Nothing against any particular seller and the person who's been mentioned a few times previously is very quick and courteous with his replies.
What do you want to achieve with a muffler swap?
Better sound? Go TTE.
Better flow? Don´t go TTE.
Better looks? Pick you choice.

Quieter on the motorway if possible, and to see if generally slightly quieter. Hasten to add that it's not as if the TTE is a thunderous beast, and I do like the tone of it, but searching through posts on here, suggests TTE get louder as they age.

Looking at the inside, that seems pretty well proven.
The choices seem straight forward, depending on the resp. weights of the individual priorities, preferences and budget.
If the latter is no issue p.e. there are wonderful sounding, none too loud, good flowing resonated ones in titanium available in Japan.
Quote from: mr2noob on November 5, 2019, 16:07Does Fox have a better flow?
No idea.
QuoteAnd does that even matter if the midpipe is stock?
Not all thát much but the OEM cat seems to flow not bad, better than the TTE.
But hey, again it is just waht your aim is.
QuoteI don't want to lie under the car and screw around with changing the pipe every time i go to MOT, the last time I changed it was a bloody PITA, I don't want to go through that on a regular basis.
As I wrote priorities and their respective weights.
There is no absolute ´best´ in it other than that OEM is the best compromise and top notch quality; any improvement in one aspect costs more than that in other areas.
The TTE is a perfect example. It flows worse, is worse quality, costs more, looks and sounds better.
Mine flows like a sea-lion on a soapy water slide, but has no cat and mán is it noisy.
Pick your poison. There is no best.
One thing I can say about the Fox for certain is it's heavier than the standard exhaust, the extra tip alone weighs 2kgs but they're twin skinned, my oval ones are at least.
