HKS Single exit Backfiring
Hey I recently put on the HKS single exit cat back and since then I've been getting a popping sound, what I imagine is backfiring on sometimes lift off of throttle and cold starts. Didn't see anything in search of it but is it just running rich? The gas mileage has not taken a hit.

Its the extra JDM air that comes in the box that's burning off..

My setup back fires. Can't say I really care for it though.
