well i finally started up my car after taking the airpump off, and putting on pulley kit and midpipe. damn its loud!!!! one thing. it smells like ****! is this normal???

No air pump and no cat. It will stink, get used to it. https://www.nopistons.com/forums/pub...#>/biggrin.png

ok my car is running like crap at idle.when its warmed up its fine. but if i rev it up. as soon as i let off the throttle a puff of smoke comes out the exhaust. its not coolant. i believe its fuel. how can i fix this.

p.s. when i drive it it backfires like hell!!!

expected

i need to get this **** tuned. im tempted to go in to debt again to get a pfc but winters a comin!!!

Are you getting any creep with the midpipe?
