@folkdoing manifolds for engine bay heat and sound over headers . If i did headers be manifold replacements. Got a 50series delta flow original grey case muffler . . Or a chambered exhaust turbo tube . Both 3" in/out . Using a flowmaster y-merge unit .
Its a stock 5.3 non emissions and pcm tune . No hard part upgrades . Just a clean cruising ride .
