for cheap you can have them chop out the stock muffler, weld in your muffler of choice and be done with it, thats what i did and I love how my truck sounds. threw a cheap black chrome tip at it here not to long ago and im a happy camper.

I did the same thing and it sounds so much nicer.

I was looking, and for a $50K truck the Denali does not appear to come with a chrome exhaust tip. I cannot find if there an option for one. If this is true, shameful, a chrome exhaust tip should be standard on a truck of that caliber.
