yeah im runnin aa aftermarket muffer which is free flowing muffler and a tailpipe that runs in factory location. the codes have been reset several times. its showing that the o2 sensor is bad. i figure that is part of the trouble. i had replace the intake gasket not to long ago and noticed the truck...

i made a stupid judgement call on my part and gutted out the cat cause i thought it would help out some performance. well since ive done it the truck seems to have lost some of its bottm end, its kinda sluggish on take off. is this due to the cat. i plan on putting a new one on and run some duals on...
