Hi - I'm a newB here.

The muffler on my truck is on the way out. I was thinking of replacing it myself. I'd like to have the best performance and a little bit of rumble from more or less a direct replacement muffler.

Any thoughts on which unit to use?

I can get this - pretty easy - but I'm not sure if it will fit? It's 14"

It will if you go to a shop and have them weld it in for you. I would suggest an 18" for you though.
