I have a 3 1/2" system and can adapt to what ever size just wanted to know a good free flowing brand at a good price.It only has a 16" resonator now.

 

I replaced my stock muffler and resinator . I went to Ryder1-770-277-9629 for a straight thru design. Part Number W26 MO85171. (3014302)Donaldson.This was shipped to my door for $69.47. This muffler is long. The stock muffler is a slight offset. Any Muffler shop should be able to hook you up. It takes an adapter because the new muffler is 4". I believe it is not any louder than stock and construction is quality.I got the reference from here and I was very happy.

 

I would say don't go with the MBRP 4' turbo back. It sounds really good around town but once you get above 60-65 it drones on and on. Most of my driving these days is around town so it's not that bad but all things being said I wouldn't get this one again.

 

I withdraw my comment. See why here -> https://www.dieseltruckresource.com/...97#post2435197
