Which muffler?

Does it make a difference what muffler you put on the 6.0 Denali? I like the sound of the 40 series but I was advised to put on the large displacement muffler-the 70 series or big block muffler. :confused2:

the bigger the muffler, the quiter it will be. The BB series is very mild.

My old man has the 50 series on his Nali' XL... sounds perfect IMO.

So the only difference is sound? There are 2 50 series, one regular and the delta flow. I am just so confused between the options. what about performance, are they all the same?

Delta Flow has less interior noise.
