my 4" straight pipe is WAYYY too loud for my liking. I would have rather kept with the stock pipe knowing what i know now. Possibly gutted the stock muffler if anything, but egts were never a problem stock.
I'm looking into a 4" muffler (which may negate the whole upgrade to 4" exhaust, making it an expensive moot point).
Nonconformist. Functionality over bling.
My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.
