Just got an 05 denali xl with the 6.0, and ordered a spectre cold air intake. Next I would like to do an exhaust I dont want it to be loud but still sound nice when you step on it. It has to be able to go on long road trips without being annoying. But i also want something much less restrictive then stock to help my gas mielage. I was thinking about about just swapping mufflers to a magnaflow and a nice tip (about $200). Is that going to be a good set up or should i consider ordering a full cat back system? I'm on a budget
Also without going the cutom tune route, what programmers do you guys reccomend?
