Put this one on my truck and boy it sounds really good now. Threw a nice big exhaust tip on as well. I can tell my truck just gets up and goes a lot easier now with much less EGT's as well. Would advise for the person who doesn't want to buy a full exhaust while opening up.

Very happy with the muffler delete for my 02 F350 7.3. Super easy install cut off old muffler with sawzall, slipped delete pipe in place and welded it in. Took about half an hr total install in the drive way. Sounds great too, glad I didn't spend $250+ on full exhaust that I didn't really need. 3.5" will suit my needs just fine and gave me the sound I was after.
