Just thought I'd get some input from people... Went to the local exhaust shop this morning to enquire about a cat back system for the ba... And from what I've read here every one goes either twin 2.5 or single 3.5... This guy recommended single 3 for mine... He has looked after me before and my dad also, so I rust him... Just seemed a bit different to what I had read before... So any thoughts on the single 3 inch system? Not planning to do any mods power wise later either... Just after a good sound...

Might just do something with the middle section and then a twin set up out the back... Link to comment Share on other sites More sharing options...

turbotrana Member 2,586 Member For: 21y 9m 18d Gender: Male Posted 18/12/13 12:08 AM Share Posted 18/12/13 12:08 AM The original exhaust is 3" (on the FG it is). Just do what SHPanda said. Even for a stock car the exhaust can be improved. If you had a Euro FG the restrictor ring would be the first thing. 1 Link to comment Share on other sites More sharing options...
