ThatGTguy Posted September 26, 2017 Share Posted September 26, 2017 Hey, this is my first post. I was just wondering if it was possible to put a catted downpipe on a stage 2 tune with a cat less downpipe already on it. I've been looking at this car for a while but that is my only concern. Would I have to re-tune the car? Or would it be ok to just put a new down pipe in? I just hate the sound of the cat less exhaust. Thanks guys.

MilesA Posted September 26, 2017 Share Posted September 26, 2017 Try and get a high-flow cat and exhaust backpressure will not change much. I think what you want to do falls into the "not optimal, but should be OK" category. It would be a bad idea to go the other way (put a less restrictive exhaust on without tuning).

ThatGTguy Posted September 26, 2017 Author Share Posted September 26, 2017 Awesome! That's what I was hoping. But I wasn't too sure. It's always better to check. Thank you. Link to comment Share on other sites More sharing options...
