Nice. I love the duramax. Comfortable and it will haul ***. I drive it whenever I can lol.

Okay guys I straight piped my truck. Yes I agree it is very loud when starting up raps and everything but then seems to be mild. I really wish it wasn't so loud during start up. Since I live in town I might have to throw a glasspack on. Hopefully that tames it a little.

I have an 07 with the 4.6 and I love the sound of my straight pipe, sure it backfires a little when I rev it up on the cold side, and cold starts are loud as all hell, but I love that sound.

I put a glasspack on and it really doesn't make it any louder than stock imo. If anything it has a little bit deeper tone but not much louder at all. No muffler at all will be a nice loud and throaty sound even with 4 cats.

Yea I just had a single 28" glasspack put on that could be why I really didn't notice much of a difference

Ah that would probably be the reason. That's a really long glass pack... Mine are 12" each, I went for the shortest ones possible.

Cheapest exhaust I've ever done lol. Sounds good and everyone that heard it likes it. Except for my father. He's old school and says the noise needs to match the hp. Which is true. A nice built motor sounds amazing. Used to have a 72 cuda with a fully built 340. Numbers matching. About 600hp. Retarded loud.
