Muffler Delete

Hi, I'm sure this question has been asked 1000 times, but I have already deleted the cat and I was wondering if any problems would arise if I deleted the muffler as well and put a straight pipe?

Correct. Only problem you may have is emission testing... *IF* they ever start looking for it. So far, it's only rumors. I kept my original exhaust in the garage just in case.

mbrp sells a muffler delete pipe.. but i'm sure you can go to any muffler place & they'll weld a pipe in for you right there. i definitely will pass doing this if it gives me crappy fuel mileage though

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.
