I have a 6.0 silverado. i want to know what the best set up would be for exhaust and headers. Thanks

 

Pacesetter LT's are the best bang for the bucks, and its just prefence for the muffler. I'm looking for a muffler myself, but not sure which one to get. I want the deepest sounding one I can get with a cut out. I've got issues to deal with on my truck first.

 

Hmmm I think some PS LT's outfitted with a custom Y-pipe or H-pipe followed by some Quickflow racing mufflers will suit your taste.

(if you go this route there is no need for cut outs, as the Quickflows give you the same performance increase as the cut outs.) But, Open headers do sound BAD ***.
