Got a de cat pipe to fit, just wondering if anyone has heard of any problems with the lamba probes sensing the emissions are wrong and / or dose the engine management light come on?

Its a supersprint decat pipe and it has the fittings for the lamba proabs.

cheers in advance.

Fitted the de-cat,

no problems at all, and what a difference!

The best mod ive done.

Glad you are pleased with your new mod. Dunno about the technical stuff me, doesn't matter with a diesel.

Seems like everyone else is too busy answering polls on whether they leave the bog seat up or down.[]

What are the noise levels like? Any chance of a sound clip ? []

I think this is something Im going to have to do now - is there a Milltek part available for my 2.5" Turboback?

 

[stokeballoon]

Just thinking the same!

 

[evilhomer]

Unfortunately I don't think Miltek do the de-cat pipes.. they are too busy trying to sell their ?700 Hi-flow cats!!!

Looks like i'm goin for the full supersprint now including de-cat!!!

What happens at MOT time?, aernt you supposed to have a Cat on a car after year 1991?

 

[GaryM]

MOT time = bolt cat back on!!

 

[andymac]

reido - few questions

how much was it?

where did you get it?

have you fitted with a standard 4mot exhaust?

 

[GaryM]

Has anybody got any recommendations for a company in the Manchester area to manufacture a replacement cat bypass pipe so that I can easily swap my Milltek cat over with the bypass pipe?

Milltek do or at least did do de cat pipes for their systems. Give them a call. They were about 50 or 60 quid. Walrus has one on his IIRC

 

[GaryM]

Ah, thanks Rich.

I was going off a post by evilhomer stating that they didnt do them.

So I assume the Milltek DP and Cat are bolted together via a flange or similar to allow easy fit and removal of a decat pipe?

 

[R1GTI]

from what I remember it is a flat flange at the dp/cat join. can't recall if it's a flange (mmm I like that word) or a normal tube clamp at the next part. Removing the first silencer box is also a goodun if you don't want to take your cat off. or do both!

[GaryM]

Oh, the cat definatly wants to come off!!

Now the centre silencer - thats an idea.....[]

There will be nothing left of this expensive exhaust when Im finished!!

So I take it u guys are swapping the cat back on for the MOT then?

That would be the plan in two years time.

Blueflame do de-cats, don't know prices though...

Where does this onbolt at the front? Does it have stud breaking potential?

Cheap way would be to sleeve a stright piec of tub in place of the cut ( Hack saw it off... and sleeve the CAT back on tfor the MOT)

What sort of gains can be expected for a 1.8T doing this?

Hello All,

Well I have a de-cat and no centre silencer on a milltek system.

I have experienced no problems and have been running it for nearly two months and covered nearly a thousand miles, what I have is a 3 inch downpipe straight onto the 2.5 inch system.

Performance wise I have not had a chance to get the car on the rolling road and have also not had it on before this pipe was done with a correct reading so cant tell the exact improvements in BHP terms, what I can say is spool up is improved as is top end and as stated below you get some more noise.

Noise wise it is not loud at idle or pottling about but once you hit 3k on WOT it gets nice an deep, you can also hear the turbo working and I dont mean wistling its kind of mechanical and I like it, it gargles a little bit but as yet no back firing on my APR chip but a small back fire on standard map on a trailing throttle which was odd.

Cost wise the downpipe and conneting to the standard cat back system cost ?129 inc VAT from milltek, the centre silencer straight through pipe was ?55 I think again from milltek.
