Would puting on a new exhaust make the car run a little richer from the lack of backpresure? I put on a Dynomax Turbo Flow exhaust las night and the exhaust smells alittle rich. I dont know if its from the new muffler or what. I’m not too familiar with that shit so…:gotme:. It does sound really nice though woot. ---

its probably just heating up for the first time and burning off anything that may have been on it. just my guess, could be wrong tho. i dont see how it could make it run rich because of the back pressure. ---

yeah thats what I thaught. I noticed it smelled alittle funny when it first heated up, but its not as bad now. But like I said, I dont have much if any real experience with that shit so I figured I’d ask. Only way to learn ya know. ---
