New exhaust

Getting a new catback system tomorrow, was thinking about a y pipe with no muffler but not too sure how loud that would be. Guess I'll just go with a performance muffler with dual exhaust, $375, didn't think that was too bad...

Cool

Leaving the muffler off or using to large of a muffler will cause you to lose torque in the bottom end. You need back pressure in the exhaust system to have low end torque to get your truck moving.

Tryed the no muffler thing before yah not a wise idea way too loud.

The y pipe alone is good enough for the back pressure the muffler helps a little but on that same note I'm running an aero3030xl and the design inside it accelerates the exhaust gases so in turn it lowered the back pressure a tiny bot and didn't notice a thing

As long as the cats are still there it should have enough back pressure. I've run with no muffler for 4 years. Torque isn't an issue in my rig. The exhaust dumps out in front of the rear tire on the passenger side so it sounds nice in the cab, even with the windows down but I wouldn't want to be passed by it. It will rattle your dentures right out lol

I do have to short shift it in town when cops are out to keep RPMs under 2800. It's not loud at all when I do that and I can usually keep up with traffic flow pretty easily.

Cool

I have no cats and I use a single glass pack with dual pipes exiting in front of the right side rear tire. Sounds good even when the MDS kicks in.

Let's assume I want to go with the y pipe and delete the muffler, does it make a difference in sound or loudness if the y pipe is closer to the catalytic convertor or moved closer towards the axle before the tailpipes separate? I really like the sound of some of the Hemi's that I have heard but don't want that crackling sound either.

Ended up going with the Magnaflow, it is actually louder than what I thought, I think I will be satisfied with this setup.
