I think I want to put a Magnaflow muffler on my truck rather than spending a bunch of money on a cat back system. Anyone know which muffler I should get?

I originally got the biggest one that would fit under my truck, Once I added headers it sounded terrible. It sounds like a motor boat outside, but sounds great inside Im moving down to smaller one now.

Well you've already dumped it on the whipple/nelson......get a cat-back with a 22" muffler....$390 isn't that bad.

I don't know which model I have but it flows great and sound pretty decent too. It's not one of the shiny ones though. Just an ugly oblong thing about 20" long or so.

I will take a look and see if I can find any #s on it tomorrow.

Lets say I want a dual in, single out, to fit up with my existing pipes. And I want a 5x11x22. are the in pipes 2.5" and out 3"?

i thought that the denali had a dual inlet and dual outlet muffler from the factory. i think that the ones that are th hd muffs will fit in there and use the stock outlet. i think you need the one that is 3" inlets.

FL8Z71- do you have a muffler on the same truck with the STS setup?
Cause I thought I heard some people say you dont have to run a muffler with the STSs, is that true?
