hey what are your opinions for the best gsr turbo cat-back exaust systems. It has to be at least 2.75" in diamiter. Thx

 

Thermal...

 

Yeah, Thermal 3" cat-back OR have a custom one made complete with 3" cat! Cheaper and better. However, if you aren't a big fan of custom exhausts, then go your own way... if you are interested, ask me for full details.

 

thermal 3" - if you have the money

custom piping - probably won't last as long but much cheaper
