What muffler/exhaust system are you guys running?

[Silverstang84]

Hey. I have a single cab Dually long bed and I'd like to upgrade the muffler for better sound and a little better gas mileage.. I'd like to go with a bullet or glass pack style muffler because is the least restrictive... pretty much straight through. I was lookin up under the truck and noticed the muffler is 2 in 1 out.. So that may mean I have to get a chambered style muffler instead of a straight through design... So, what are you guys running?

3" in 3" out dyno Max race bullet. I like the sound and the price was right.

2 single in single out flomasters, if I had to guess I'd say 2 1/4 in/out. Can't hear it at all while driving, sounds good when my wife pulls out the driveway though.

Don't know what it did for fuel mileage, came on truck.

No cats, 2 single super 10 flowmasters. true duals with 4x24 inch tips. sounds good, not just deafening but sounds mean, it has just a little pop to it just as you approach WOT. VERY deep exhaust note.

You can have a y pipe made or purchase one cheap to to fit one single muffler. A muffler shop shouldn't charge more than $70 installed for a single glasspack like that. (Including the cost of the glasspack)

I have a 3" Dynomax cat back system. Love the sound, quiet enough at idle, but gives a throaty sound when you get on it.
