RastaMc Posted October 25, 2011 Share Posted October 25, 2011 Hi guys. I'm looking for a new exhaust and I want to know what's the difference between a cat back for a TT and for a N/A. If both are installed after the 2nd cat/decat I don't expect any difference. However there is, e.g. a Nur Spec R for a TT and one for a N/A...with different price. Am I wrong?

merckx Posted October 25, 2011 Share Posted October 25, 2011 As far as I'm aware a TT aftermarket exhaust would be too loud on a NA, the turbo's do help to reduce noice levels. Link to comment Share on other sites More sharing options...
Kirk Posted October 25, 2011 Share Posted October 25, 2011 Its the size of the piping. TT Nur spec = 3" NA Nur spec =2.5" Link to comment Share on other sites More sharing options...

Preparing for the future (maybe a VVTi ) I would chose then a Nur Spec R for a TT. Thanks guys! Link to comment Share on other sites More sharing options...
