I have 2002 with a problem a can't pinpoint. Theres a noise that sounds like an exhaust leak while i accelerate. I tried lifting the rear wheels and accelarated while checking out the engine bay, but can't seem to find the problem. After i crashed and rebuilt the truck, i noticed a broken bolt on one of the headers. I swapped the headers to long tubes but that didn't seem to be it. The headers were the last of the exhaust to be replaced, i have new tubes, headers and cats. Any ideas. Sound seems to be coming from the drivers side
