markyp Posted November 1, 2005 Report Share Posted November 1, 2005 Can anyone advise me on pros and cons of fitting a downpipe decat onto my mapped Mk4 turbo. I have already had it remapped. I know the problem of MOT time! My car is the earlier engine type with a single lambda sensor before the cat. Thanks all! Link to comment Share on other sites More sharing options...
Avus_Bub Posted November 1, 2005 Report Share Posted November 1, 2005 Apart from the emission issue......... Cough! Cough! You should gain a bit of midrange torque - better throttle response and possibly better economy. BUB Link to comment Share on other sites More sharing options...
