well thats basically it any one run straight pipes with the stock cats? or i guess its the same as a cut out?
if you do, do you run a tuner? any issues with not runing a tuner? will it run to lean?
my biggest question is will it void my warranty?
im thinking doing what i did with my old f150 with the 5.4 just take the exhaust off and run a pipe back with a 90/45 on it pretty much an mbrp turn down with out a muffler.
maybe i missed a thread discussing this but i dont see any. so whats every ones oppinion on this?
