is ther such a thing as a muffler delete pipe or do you just replace with inch inside dia pipe??
Depends on the truck. A straight pipe 6.0 can sound completely annoying or down right mean. On my 7.3 with a 4in turbo back exhaust WITH a magnaflow muffler sounds like a kitten. Not loud at all.
When I was testing my new stage 3's, I only had the down pipe and 3 feet of pipe connected. It sounded horrible to me. Ever heard a high compression engine running on small glass pack mufflers? Very loud "Bark"? That was it.
Talk the the board vendors about a muffler delete pipe.
