i have a my00 2.5 rs (38,500miles) and i installed a bosel/brospeed/SPT exhasut. it seems to me that the car is now backfiring between some shifts or when there is throttle lift. it isn't very loud but it is noticeable...another thing is i think the car is runnign kinda rich becasue they is soo much soot on the exhasut tip is t rediculous.
is that normal for a scooby? my altima never had soot (carbon build up) on the exhaust like that and it has 140,000 mile on it
can anyone give me a few ideas of what to do?
