I have been thinkin bout what the cat-back w/ no muffler sound like? Does anyone have a clip from an 06? I would like the most whistle out of the exhaust as possible. A 6slow passed me yesterday and all i could hear was his turbo singing!! Will my truck sound like that since they use the sae turbo?

I cut the muffler off of my 06 and left the cat in. Turbo is much louder out the exhaust pipe now. Exhaust tone did not change any, it only seems now that at an idle the exhaust is flowing much more free as you can really hear the air coming outta it now.
