I got a 2005 4x4 CC with 84k miles. The exhaust pipe rusted and snapped off. I cut it flat at the muffler and it has been fine. However, this combined with all the cracking of manifolds and cat failures have me thinking of just removing it all and starting over. I live in a a non check state, so I don't have to worry about cats, other than codes. I was thinking of stillen long tube headers and a new exaust system? Not sure which one. Looking for some recommendations here, not doing it strickly for performance, just the stock system is so crappy and I plan to keep the truck for a few more years. Based on what I have read, I am starting not to trust the stock cats.
