Ever since i got my headswap and offroad h pipe the exhaust makes a popping noise at idle. I don't ever hear it when im driving around but at idle it sounds like im popping popcorn. The weird thing is though, it only does it out of the driver side pipe. Anyone else have this problem. I can also smell a strong gas odor. Does this mean I am running rich? The next thing Im doing is getting a dyno tuned chip because i still dont have one since after the headswap. Any help is aprreciated.
