I've emailed Che about shipping costs to the UK - will let you guys know.

Markiii - any issues as far as you can see from the pics?

Post by: Slacey on March 10, 2006, 10:58
I've had a look and I can't see any problems. Nice nit of work IMO - Che's products are 100% spot on so far.

For a difference of $25 - price for the first ten compared to subsequent group buyers - I reckon that would be a smart move. Thanks Tem.

I don't really see the point of this as an alternative to de-catting. All the hard work in doing a de-cat is in removing the manifold from the car and re-installing it. Actually removing the cat material from the manifold is the easiest part, and by far the most satisfying    s:wink: :wink: s:wink:  

Picture Norman Bates style stabbing motions through the O2 sensor sockets with a long screwdriver :-

"You", stab, "destroyed", stab, "my", stab, "engine", stab, "you", stab, "b**tard!"   s:twisted: :twisted: s:twisted:

It was so good I needed a cigarette afterwards, and I don't even smoke.   s:D :D s:D  

Personally I'd rather keep the approx $300 (inc shipping) and spend it on something else.

It looks to be a copy of the TRD header... and a well-made one, as best as I can tell from the pictures.  The price is excellent.  It would be nice to know the noise level compared to stock, gutted precats, and TRD header.  The TRD header has a smooth inner layer and I don't know if this one does or not.  That could be a factor in noise level and exhaust gas velocity.  I say it is worth a try at that price.  I sure am glad I sold my TRD header already.   s:) :) s:)

OK, had a reply from Che and the total cost to the UK is $275.00. Import duty would of course go on top if this.

That's not bad value at £160 or thereabouts. Be interested to see the real world benefits over a gutted precat manifold.
Already accept that it looks a whole lot neater.
Some guys on spyderchat think that  pipe no.1 is longer , but Che says they are equal length. What does anyone else think? Does it matter that much? or is the photo of the header a bit misleading?
Title:
Post by: Anonymous on March 11, 2006, 00:19
I dont think that the photo helps.
From what I've heard about Che and read on here after doing a search, the products are generally top notch, and I havent read of many with problems. It's not going to be TRD good, but is a good copy. He is offering a 12 month guarantee and a refund if any problems too, so looks like a good option to me. (Wish I had known about this before getting pre-cats gutted this week!)

Cheers

Roo.

I'm going for one as my manifold is not very nice after having to drill and tap all of the bolts. I will keep you posted when it turns up

Post by: Chris on March 15, 2006, 09:51
that is mega cheap, as i'm guessing it's quite heavy, so i thought postage would be huge!!!

Weights 7.5 lbs according to Che, which is 8.7lbs (nearly 4kg) lighter than the stock one.

I've ordered mine tonight...

The benefit is that there are no sudden diameter changes, as there are in a gutted manifold. The Che manifold should flow better, which should in turn be better for power.

Hi all!

Just a quick idea as an alternative, I checked the price of this manifold and delivery and for just £25 more Hayward and Scott will build and fit one for you!

Worth considering if you can get to them!  Also cuts the risk of it arriving bent or summat since they don't offer insurance on the postage!

That sounds good value at H&S, so they said £185 for a custom manifold?
Title:
Post by: markiii on April 21, 2006, 12:49
very good, it was nearer to £300 last time I asked

is that definately an agreed price?
Title:
Post by: Two's Company on April 21, 2006, 12:58
How much of a power increase could be expected from the H&S compared to gutted pre cats due to the smoother air flow etc?

Post by: Anonymous on April 21, 2006, 15:46
if youre looking to get a custom header made maybe get H&S to make it more like the brad bedell header ;-

Not quite sure what primaries are.... but Che assures me all the pipes are the same length on the Che header also.

I would like to see the Che header in the metal - from the photos it definitely looks as though the pipe which comes up from the left hand end, over the top of the other pipes, is significantly longer than the one it joins to.

Just to make things clear I was quoted £223 for the CHE manifold including shipping and £250 from Hayward and Scott (supply and fit) They said they don't have a pattern for the manifold so they'd need the car!

Does anyone know of someone who actually has an aftermarket manifold fitted (with pics if poss.)?

If they's prefer, I can drop off a stock manifold to them, and they can have a look around my car to get an idea of the amount of space available for them to play with. This is of course assuming that they intend to make a manifold along the lines of the TRD / Che unit. If they want to make something more exotic, then they'll need the car to make sure everything fits within the confines of the engine bay. I dont mind donating mine for a few days. I can loan them a stock silencer box as well, as thats about the biggest silencer unit available for the MR2, and will dictate the maximum size of the manifold if it's to be truly compatible with the car.

Hi dodgie are you fitting your mainifold your self or taking it somewhere?  Just interested how much messing around they are to fit!

Looking forward to the pictures...

GSB, I think the best thing is to email Hayward and Scott and see what they say but I would have thought if enough people are interested they'd make a batch up if someone can provide a pattern to work from... I'd be interested anyway!

Do you want to email them or shall I?

I suspect the H&S was soo cheap as they want a development car hence the price and that once they have the pattern, they would charge a lot more for any further copies.

I saw the che manifolds on Ebay.com and it's a bit of a bargain really. I've got 1 years engine warranty with the 2 I just bought so not going to worry about gutting the precats yet but towards the end of the year, a che or H&S exhaust would be the way to go.

Doubt it. They used my car to develop the dual exhaust's that are so popular with ROC members. They had my car over a week to do the work, plus a couple of further visits for adjustments etc. I actually paid the same as the guys on the GB's.

Jamie, seeing as you have already entered into discussions with them on the subject, then you can e-mail them. Give them a brief run-down of the pre-cat problem, and detail the requirement for a manifold that would hook up to the stock exhaust system. Give them some clue as to the possibility of future sales through the Roadster Owners Club, and tell them that the guy who had the first exhaust made has a spare manifold they can borrow as a template, and a car that they can look over to see how much room they have to work with. attach a few photos of the manifolds above, i.e stock, Che, and the brad bedell manifolds.

You can CC me at the email detailed in the button below.

Just to let you know, I fitted the Che manifold last night and had no problems apart from a little manoevering with the heatshields.
Thoroughly recommend, the finish is exceptional.

 s:) :) s:)   Sweet. I was just about to ring H&S and ask about this exact thing. I guess I will watch this space. I'd like a complete H&S exhaust (back box, cat and manifold).

Hi everyone,
Well unfortunately it seams Hayward and Scott made an error with their original quotation...

"To Jamie
 
I am not sure where the £250 came from, we have never done the manifold that cheap before, maybe there was a slip of the finger when being typed, hence the resent quote of £500.  Sorry for any misunderstanding.

Regards
 
Ian Reeve
Manager"

So it looks like they are gonna be far too expensive, they did offer a discount of £425 for a group buy from the club but obviously this is still way more expensive than other alternatives.

So lets get some posts of pictures and experience of other manifolds so we can decide a good alternative.

Gonna fit over the weekend, will try get some pics up.

Post by: Anonymous on April 29, 2006, 16:02
Fitted, cats are fine. Had a few hassles such as top heatshield bolt breaking in the old manifold and getting the heatshield and O2 sensors back on again are a bit of a pain coz the manifold differs slightly from stock. Also make sure youve got both long & short 12 & 14 sockets with extensions and Id recommend buying the gasket set from Toyota because the supplied manifold to head gasket doesnt look like it would seal properly (totally diff to stock version).

Gasket part nos as follows: Manifold Gasket - T17173-22010 £14.05
Exhaust gasket (rings x2) - T90917-06065 £2.76 each

Definitely revs more freely through the entire range and has a nice deep throat sound when you put your foot down, although when driving miss daisy it sounds pretty much the same as stock.

Ive driven 60 miles with it on and im very happy especially considering it costs next to nothing compared to any other manifold.

Only let down at the moment is Im tending to put my foot down quite a bit just to hear that sweet sound!

P.S dont work in the dark at 10pm without a torch on a black car! Youll get away second best with loadsa cuts!! (I was determined to get the job done)

Did you buy the manifold from ebay or did you deal with them direct?

How much did you pay (how much was postage?)

Dealt directly with Che via email.
£166 incl. postage, marked as a gift so didnt get nailed with customs charges.

Cheers mate,

Just been reading another topic on the forum about the quality of this product, how are you finding yours?

Upon waying up the pros and cons of fitting this manifold or de gutting and refitting the standard one where does everyone stand?

Is anyone gonna take H&S up on their offer of manifolds at £500?

Jamie

Nope, I would have considered it at the £250 that was mentioned but turned out to be a mistake!   s:wink: :wink: s:wink:  

Whether it is worth the money depends on your reasons for changing the manifold.  If it is for a performance increase a Unichip will give a much bigger improvement for the same amount of money.  If you just want to get rid of the pre cats, I would just gut them or if you don't fancy that get a Che manifold.  s:) :) s:)

Just had my Che manfold fitted by Silverstone Performance. I've only done 50 or so miles on it, but I can agree with Twist completely. Not a massive noise increase, but definitely noticeable when you floor it.

Plus, it just looks sexy!
