  1. Does the aftermarket GM performance exhaust have an option for using factory tips? My dealer said there was no GM Borla option that used factory valance tips but clearly those from the factory do. I’m in a 2020 SLT X31 5.3L 10 sp
  2. Who’s running these? Can’t find 1 review with the new Fox 2.0 front & rears installed on a ‘20 gmc or Sierra 1500. Sick of waiting on Bilsteins so lkg to install on a ‘20 gmc 1500 SLT X31. Front Coilover: 985-02-134 Rear shocks: 985-24-209
  3. I’m in SA. The part for my crew cab 84742428. The link you posted is 84538238 which is for a double cab. https://accessories.gmc.com/product/crew-cab-sport-step-assist-steps-in-black-with-sierra-script-84742428?year=2020&make=GMC&model=Sierra 1500&modelId=548&body=Crew Cab Pickup&bodyId=22&wheel=Short Box&wheelId=651&trim=SLT&trimId=296&drive=4WD&driveId=8&engine=5.3L V8 GAS&engineId=2059&bodyNumDoors=5
  4. Rotofab here on my ‘20 gmc 5.3l 10sp X31. Love it. Excellent build quality, perfect fit & finish, no issues throwing codes, and legit getting about 2mpg increase. Averaging 18.5mpg over 2000 miles and driving like I stole it, no babying the throttle.
  5. Hey there.  With regards to the RotoFab CAI for the ‘20 GMC Sierra 1500 5.3L as opposed to the factory GM CAI upgrade.....the GM installed CAI gets a dealer tune/recalibration.  What is this recalibration that is being done with the Gm Cai that I’m not getting if I go the RotoFab route?

    1. Roto-fab

      Roto-fab

      While we can't speak for any competing products, I can tell you a few things about our development process:

      During development one of our main goals is to produce a system that will perform great on the factory calibration. This is no easy task, especially on newer GM vehicles. We implement unique development and prototyping methods which allow us to test over 100 different configurations on the road and track. By closely monitoring and logging pertinent data over the course of many months, we arrive at what we consider to be the “perfect” cold air intake for the vehicle. Then we tool up for production and prepare for release. At Roto-fab, the constant chase for perfection is the real motivation for everything we do.

  6. OK....but this screenshot has been saved to my phone since before I bought my 2015 All Terrain, well before the X Package was even announced.
  7. Damn, poor bastards who paid $5k for a performance off road package that can be had for $900 of existing aftermarket parts. Smh
  8. The part numbers for this "new exhaust" you've listed, have been available through the GMC public performance parts website for several years, so if this "new" exhaust is what is being put in the X package then this is all just a marketing scam. I have printouts of this exhaust option from 2014. So if 6 GMC dealers and GMC customer service have all been unable to tell me what the new exhaust is that's put in the X is this option, I can understand why they have avoided answering it bc it's just an existing option. What I don't understand is Borla's corporate engineering office telling me they've designed the GM Borla exhaust and a new, GM Borla exhaust designed specifically for the '16 all terrain X. It also makes zero sense that a brand new truck would leave the factory with an exhaust that was going to have to be replaced and installed by a dealer. Sounds fishy to me.
  9. Would you be able to post the part number here? What dealership do you use?
  10. I asked parts that exact same question and they said a) they can only order parts based on their parts books which can take months to update on new vehicles and repairs can be delayed and b) they didn't know if the exhaust was tweaked with different air intake and some tuning to get HP bumps on X package and may or may not work on other Sierras. Baffling so many dealers can't address this for those looking to maybe spend some new $$ on a new exhaust like me and want to know all options that won't have droning.
