Re: Help! Bolt in exhaust pass through?
I'm pretty sure he's talking about frame twist without bolting or welding in tube support after cutting cross member . I just cut 4" holes and welded in tube support total cost was $20.00 for the tube . A lot of these old trucks have "chevy twist" in the frame with stock engines ,So throwing a 1000 at a stock frame holes or not will probably have the frame looking like a pretzel .
