    Sounds good man. Just bought a 6.0 gas from someone who had to have the cats cut off because they couldn’t replace the factory ones that were clogged up, and was thinking about doing an exhaust for it and couldn’t figure out what I wanted to do to it. So this helps me figure out what it would sound like and how I need to run it

    It’s hard to beat the looks of these trucks. That truck in Alabama with no rust would bring around $7500 in good condition.

    As long as it has a cat in each pipe coming from the manifolds then dual pipes all the way out the back then it’s “true true” duals. Having cats doesn’t change that.

    Good video man! I just got a 03 Sierra 2500hd with the 6.0 in it. I’ve got essentially the exact same exhaust as yours on my old 05 with the 5.3 and it sounds awesome. I just recently had a flowmaster single outlet put on my 6.0 and it’s got an obnoxiously loud sound from 1500-2700 rpm’s and I’m not gonna leave it this way. I’m thinking of going your route and true duals with 3 inch and no cats. Did you do anything for the O2 sensors? On my old truck I used spark plug non foulers to to trick the O2’s so no check engine light would be on. Also how’s the sound on your truck curious say between 40-55? Doesn’t help I’ve got 4.10 gears so mines cranking some rpm’s pretty quick

    Nice stock wheels, I'm always looking for those rims but hard to come by!

    I noticed chevy wheel covers and a silverado tail gate. ???

    Sounds really good some 5 or 6" tips would give I slightly deeper tone. I'm running full 3" on my 5.7 vortec no cats 5" chrome tips

    I have this same truck but its a manual 5 speed. Im tryna figure out the name or model number of this transmission
  • @asilusx24
    Your like 4 years out from grandfatherin bro, some states I think require cats and O2s and all that so it might be rough.
