Ive got an 04 coupe and am wanting to get the motordyne dual shockwave exhaust and borla headers. I wanted to know if anybody has done this and if so what kind of results did you end up with like hp gains and what not. Also considering the motordyne ART test pipes.

 

for the non-rev DE you'll need cams to get good gains from headers. also OEM cats are just gonna choke them back out again, if you can run test pipe's, get ARTs, if you can't then pick up some HFCs. a tune would also be necessary to max out your gains.

 

well the ARTs are just $60 more than the y pipe with the HFC so itll definitely be the ARTs. May wait on the cams though.

 

get the ART pipes

 

Art pipes are the best

 

Will the Borla headers fit an '07
