congden replied to joshc64311's topic in 2014 / 2015 / 2016 / 2017 / 2018 Silverado & Sierra Accessories & Modificationsdid you have the intune tuned on the truck prior to running diablews tune? Ive also got a 93 Tune from the Diablosport now and wondering what the difference would be if I purchased his tune.
We all know that muscle car sound, the rasp and sound that they all make when modded. No matter whats done to the exhaust a truck seems to just sound like a truck and you can pick the two out just by sound. Who has put a true dual type exhaust into an x pipe and back to two duals with rear mount mufflers? or any opinions on this or am I going down a rabbit hole with wanting that exhaust note.
congden replied to CFRED70's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500If you dont feel you need a V8 now and have happily test driven a V6 then buy it. I know the modern V6s are making as much or more HP than V8s of yesteryear but me personally I will never buy one. If you want to leave the truck stock forever, (no bigger tires) not pull trailers or haul more than 500lbs in the bed more than a few times or not feel the need to hear/feel a V8 then the V6 will suit your needs I am sure. If you do want to do one of those then I would reconsider.

Super 10 definetley gave it some tone. I went from the straight pipe to the 10 and didnt notice a quieter exhasut at all.
congden replied to maxum3300's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500i have -12 offset with 33" M/Ts on a leavel with a diablosport 93 octane tuned and an exhaust. Stock i would get 22-23 HWY, Before tires with a tune 20 avg. Now i can barely squeak 18 highway if i try to drive like my mother. closer to 16.5 if I drive it. id say you don't have much room at all with a lift ( kills the trucks aero, might as well be a flat plate in front and pushing 35's.)

congden replied to duquephart's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500Looks crappy IMO to have gaudy dealership stickers on my new truck. Theres a GMC dealer here in Milton, Fl that literally has full size front window stickers that say "MCkenzie GMC" on every new sierra and I see a few new sierras driving around like that and alwyas chuckle.
Yes, it was a noticeable difference, Not like headers or a straight pipe but you are considerably freeing the exhaust flow and changing the pressure around that area. If you didn't care about warranty on the exhaust I would cut the whole 3rd cat section out and weld in a new pipe to smooth out the flow and eddies caused by the now void 6"x 8" "chamber" in the exhaust. I left mine because if I have to bolt the stock exhaust back up no one will be the wiser.
congden replied to EspoMan's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500So GM doesn't test or develop Silverado's or Sierra's to go over 75 MPH, test speeds limited to 75 mph per GM engineers unless its a Corvette or Camaro? Yeah.......
Don't tempt me, for sound I want to but idk if I can justify the cost for such little HP gain
