jamesmark Posted June 6, 2008 Share Posted June 6, 2008 The Stock system is far to restrictive, don't know about noise but there will be zero performance gain. Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 6, 2008 Share Posted June 6, 2008 Decatting and a stock TT exhaust is a good upgrade for a NA. Quote Link to comment Share on other sites More sharing options...

TurboBrett Posted June 6, 2008 Share Posted June 6, 2008 the cat pipe and decat pipes are a straight swap, doesnt matter what is after them;) Quote Link to comment Share on other sites More sharing options...
gordy07 Posted June 6, 2008 Author Share Posted June 6, 2008 So i could decat before i decide on the exhaust? Where can i get decat pipes and do i need to put them back in for mot Quote Link to comment Share on other sites More sharing options...
Nic Posted June 6, 2008 Share Posted June 6, 2008 So i could decat before i decide on the exhaust? Yes Where can i get decat pipes and do i need to put them back in for mot You may need to replace the second cat for the MOT which is relatively easy. It is therefore better to get 2 decat pipes to replace the 2 cats, rather than a single decat pipe that replaces both. I'll pm you prices.

It makes the n/a sound very nice! Oh and get a 2nd decat pipe too... Quote Link to comment Share on other sites More sharing options...
