Went the 2nd hand route as i want to take it out after the MOT. She runs so well without the cat clogging things up.

I bet it runs equally well with it.  Try it? Save the planet too.

I wonder how much (if) the precat that comes as part of the TTE kit has on the numbers?
Or are the numbers just down to everything being tip top.

Will be intersting to read Gregs observations once fitted.
Improved, no change or reduced performance?
Change in acoustics?

Does anyone know for sure if the SP downpipe brought anything to the party?
Mr Ts performace figures for the vanilla TTE were based on the stock cat and single exit zorst going back on.

I say that simply based on the installtion guide shows the stock zorst going back on.
Does not say, must fit the TTE zorst.

Do we have anything in the archives for a stock TTE with stock zort vs SP down pipe.
I can probably answer that with a no. But happy to be proved wrong.

Then again there was that rolling road shoot out post from years back. @spit
£5 to the club if the answer can be found.

Looking for real data not anecdotal.

From memory sp backbox took tte turbo power from 184 to 197 as was designed for turbo application.
I would expect the decat to add 5 to 10 bhp the cost was im sure £279 for the decat pipe when new.

Correct also you could fit tte turbo kit with standard backbox.

[Ardent]

  Yozzers!
In the zone. £538 to £846. Diff £308. Could be the price with or without the downpipe.

[s12vea]

Expensive options.
As you know a great piece of kit

The answer can be found and it is - as you suspected - No. So far, anyway.

£5 to the Club please!

OK, you've got me there.

We did have a member who moved from TTE and stock back end to SP but we lost track of them and as far as I can recall they didn't run pre/post dynos.

Anecdotally, the closest I can get to your scenario is ninjinski's butt dyno and take on acoustics (although this was with TTE rather than stock zorst pre and post install). This verbatim from 2006:

Just back from having the main CAT removed and the SP downpipe fitted (plus and oil change and a new seal for the TTET) and first impressions are that the downpipe DEFINATELY has an affect on performance.

I remember reading people here saying that the TTET was the way the car should have come from the factory, well with the downpipe thats the way the TTET should have come from the factory. Its that good!!! Money well spent!

The car feels smoother and revs much better pulling through much more of the rev range and the car is faster, noticably faster.

And my TTE exhaust now sounds somewhat like it used to prior to the TTET being fitted which is a nice bonus!

[Ardent]

That's good enough for me.

£5 duly pinged.

[Ardent]

Just a little bit biased, as I seem to have that setup.

This is the only setup I have known.
Stock TTE+SP downpipe.

[s12vea]

Im sure Greg can offer a passenger ride to confirm if needed, either way both of you have great setups.  :notworthy:

[H1GRM]

Yep passenger rides welcome.

So De-Cat pipe removed and 2nd hand stock Cat on. Initial CO readings were worse than before - Oops. After a good blast and getting her as hot as possible we just scraped through the test. Fast idle 0.20, Natural idle 0.22, however I am not sure that the sensor was in the right place (may be a bit of fresh air wafting!!)

The car definitely feels more sluggish with the Cat in situ and the idle is not smooth, sounds different to, a bit muted. No dyno test before or after so just going on the sensations experienced.

Oil change & filter (Millers Nanodrive CFS 5w40 NT+) De-Cat pipe refitted Goddess back to her normal self. Just needs a good clean at the weekend.

[Ardent]

Well played.

Much phaff swapping the cat back and forth?
Can feel a new game of pass the cat coming on. 

[Petrus]

sounds different to, a bit muted.

Good to read/know for my diy muffler idea.

Must get round to ordering an OBD2. Looks like the ScanTool OBDLink LX is the one to go for.... but why are they £70 to £100 in the UK and only $40 in the US and yes I appreciate the company hail from the US but come on guys, play the game.

Any one ever ordered one from the US? Feedback please

[shnazzle]

I did. Had a relative bring it over, so I paid the 40usd.

He travels quite regularly to UK so I can ask if he can bring another one over

Wow that sounds great, would really appreciate it if you could have a word.

May I, please, have one too? 

[shnazzle]

I will ask but no promises.
Would you be OK without boxes? Just because he usually packs light when traveling for business

No box = just fine.  Fingers crossed.....

Same for me

Turns out our lovely house-malaka Manos is in the US until end of Feb. He's going to drop me an address to get them shipped to. Then he'll bring them back to UK.
I'll pm you two

Out and about Friday, Saturday and Sunday and will be out again this evening in this glorious weather. Seen 2 x Two's one blue and one silver both mentioned in "Spotted".

[H1GRM]

To wax or not to wax that was the question.

Rob Marshall of Car mechanics Magazine visited "Rustbuster" in December 2017 and here is the article:

www.rust.co.uk/files/pdf/Rustproofing%20Rob%20Marshall.pdf

So as Rustbuster are only 10 miles away that helped in the decision process.

I have tried to attach some pictures but unfortunately even one is to large for the forum.

[H1GRM]

Back from Hols but at a Regional Swim Champs all Bank Holiday weekend.

Had a quick run out on Thursday but had to jump start, the radio standby was on and had drained the battery. A quick 20 mile blast proved how much I had missed driving the Goddess.

Looking forward to the rest of Summer
