Just wondering if I put a Greddy or Drag3 kit on my civic, could I keep my Comptech catback system without harming anything? All help appreciated, thanks!

 

it wont harm anything, but if you want to run big boost and make more power you will want AT LEAST 2.5 inch piping. Personally, I like the comptech exhaust and if you are just running a standard setup on the drag 3 kit it will be just fine and a fun, fairly quiet car to drive around.

 

Thanks for your help! I am only planning on running 5-6 psi tops. I love my Comptech, I was afraid I was going to have to upgrade to 3" and a fartcan to compensate for the turbo. Thanks again!
