let me just ask a stupid question, the o2 simulators....do they go towards the back of the exhaust where the hpipe meets, or do they go right after the manifolds????? i put them right before the hpipe meets the cat back, and the check engine light keeps comin on....
well i did that, and now the light still comes on about a half an hour of driving time. i dunno whats goin on, i think i still have an exhaust leak.....im sure if its still leakin a c-hair, it'll throw a code. another question, what do these things run bone stock quarter mile times......so far ive got a cold air, cat back, and o/r hpipe.....
