  1. Yup, this is for the 6.2. I kept the resonators just in case I want to quiet it down someday, but scrapped the rest. Thx on the floor, best thing I've done to the house! Sent from my Pixel 4 XL using Tapatalk
  2. I know this isn't exactly what you want, but here is the GM performance exhaust right before I installed it. Notice, no flappers before or after muffler, and no resonators. Good luck. Sent from my Pixel 4 XL using Tapatalk
  3. Agree. Too much safe space, not enough unsecured space. Sent from my Pixel 4 XL using Tapatalk
  4. I have the 6.2 and the GM Cat back. I don't understand what people are talking about with this helicopter sound. I've driven 40-50 and all speeds windows up/down everything, and I can't get it to make any abnormal sound. I'm just curious because I kept both my resonators just in case I need to put them back on to quiet it down, but I don't hear anything. Are you towing while doing this?

  5. Sorry for the crappy formatting, I copied and pasted from detailres website. MY 2020 AT4 got some love yesterday with a nice Ceramic Coating. Decon. pre-rinse Degrease engine bay Sealant foam bath Clean wheels & tires Dress plastics & tires Streak-free glass Ceramic infused paint sealant Synthetic clay paint prep. Interior air blow out Vacuum Hand scrub seats & panels Fine brush vents & crevices Clean windows, screens & mirrors Deoderizer Scratch, scuff, scrape reduction Hard water spot removal Oxidation removal Paint swirl removal Application of Feynlab’s V2.0 9H Ceramic Coating Includes 3yr warranty Covers all painted, plastic trim and piano trim panels 125% Gloss boost compared to factory new finish Ease of cleaning maintenance Cost savings by eliminating quarterly wax/ sealant
  6. Ok thanks, just wondering if 2020 vehicles are getting an update now too, or if it's just 2019. Reason I ask is, my BT is finicky when using Android auto, and the user profile load takes a long time every time I start the truck. Sent from my Pixel 4 XL using Tapatalk
  7. is anyone with a 2020 getting this? I just checked and my version number isn't an 80x anything, its like 611 or something. do 2020s have a different infotainment system with different version numbers? mine says no update available and current software is from May 2019. thx 2020AT4 premium pkg.
  8. 2020 AT4 here. Not sure how big the air dam is on other trims, but mine was only about an inch tall. Not much of a difference either way... Sent from my Pixel 4 XL using Tapatalk
  9. Flashed yesterday. It feels snappy, but honestly not sure if I can tell a difference, it's probably just placebo effect... I don't notice any additional noise from the intake, just the exhaust, and it's perfect. Nice cold start rumble, growls when you accelerate hard, but nearly silent at cruise.

  10. Here is the paperwork that came with mine. I installed myself and just had the dealer flash it yesterday, they just need to follow those directions and call the GM number. Good luck. Sent from my Pixel 4 XL using Tapatalk
  11. Installed GM performance intake and exhaust on my 6.2 AT4. Still need to make an appointment for the ECM flash, but I love the new sound. Sent from my Pixel 4 XL using Tapatalk
  12. If anything mine seems too conservative for my taste. I set it up on the closest following distance, and wish it could be adjusted further down. Same with the automatic braking, it's a little too conservative. 2020 AT4. Sent from my Pixel 4 XL using Tapatalk
  13. 2020 AT4 on Dec12th and upgrades for xmas. :-) Sent from my Pixel 4 XL using Tapatalk
  14. There is much more room under there for a longer tank, I wonder if there will be an option for an aftermarket tank someday. Maybe they saved this space for a DEF tank on diesel models, bit they should have offered a larger tank for gas trucks. Sent from my Pixel 4 XL using Tapatalk
