i just installed a 3" inlet muffler and 3" piping.all of a sudden i get greyish smoke coming out of my exhaust.when i put the bottom of my slipper next to the exhaust outlet for about a couple seconds and it gets really moist.this must mean im running rich.im suspecting my o2 sensor has gone bad or my injector wires(one of them looks burnt).where can i find the o2 sensor?how much does one cost,ive seen a few on ebay and theres 2 available:the splice in one and complete one,theres quite a bit of a price gap between the two.all hoses are seem good,no leaks,no cracks.just replaced chips from huntley to guru.so what else could be making me run rich.btw,its getting quite expensive to put gas around my area now,so i want to save as much gas as possible.( 92 octane,chevron w/techron=$2.24 )any help will be appreciated,thanx

my exhaust has a faint gun powder/sulfer smell to it, when the car is under a load.

I have the exact same problem. Guru chips 3 inch cat back and ever since the exhaust I have been getting a puff of white smoke out the back.

I would love to know why this is happening. I have a new O2 sensor on my car and also new throttle position sensor
