I got a standard heads going back to standard CATs the from 2.5" exhaust to 3" to back to a Dynomax super turbo muffler and back to a 3" tip. I wanna rip out that dynoflow and getting something louder!
My truck came with a Flowmaster 40 minus the front cats but when the backs went I just whacked them as well since it was cheaper... If you're in a state with emissions you can't run either setup, but it sounds great
With just the fronts off
