I noticed the 2016 GMC Sierra All Terrain X package includes a performance exhaust upgrade. Does anyone know what's different about it?

I thought it was just the GM performance parts Corsa cat-back system.

Picked up a new 2016 All Terrain X, at first there was no change in the exhaust sound. A few days later the dealer called and said I need to come pickup my "muffler" - which is a dealer installed item that was supposed to come with the truck. Turns out its a complete cat back exhaust, the sound is much louder, but no drone and quiet when light on the throttle. Sounds just right. Came in a large box - I could try to get the technician to provide more details or I can post pics if needed. Also they gave me my stock exhaust to bring home.

I would be interested in any more information that you can get. Thanks!

The GM Performance Catback is made by Corsa for GM. These are different than the Borla GM Catback. Just one style system, which is single in/out with a passenger side exit. They are warrantied through GM rather than the Borla one which has the Borla warranty, and not a GM warranty.

Thanks for the information. Is there a part number for this? Can you just order one through the dealer?

Again, these are the Chevrolet/GMC Performance Parts catback (made by Corsa as the boxes have TMG Performance on them, the parent company of Corsa http://www.tmgperformanceproducts.com/index.php).

 

The GM By Borla is available for all cab configurations, where the GMPP systems are double and crew cab only.

No love for 6.2 double cab standard box?

 

 

Look at that list again...Double and Crew Short share the same wheelbase hence the same exhaust package part #.

So does the Corsa system have a flapper valve too? How do they eliminate drone?

 

How about exhaust tips? Do the Corsa tips come with it. They have the best tips IMHO.

I can't speak for drone on the 1/2 ton with AFM, but on my 15 HD, zero. They have some trickery within their mufflers:

Do I believe them? Yep. I've had mine on for 12k miles, zero drone. Zero.

 

It is tipped yes, but I believe it is Bowtied (Chevy) or GMC'd (GMC). They etch it on the tip just like they do the Corsa logo on all their other stuff.

I think this thread is headed in an uninformed direction. I have spoke directly with Borla, and they designed the performance exhaust for the '16 all terrain X specifically for this truck. It's not the same as the GM Borla exhaust you can order for any truck through GMC performance parts and it's NOT the 1 made by Corsa. So far, you can not order this exhaust, it only comes with the X package on the new truck.

What if you own an all-terrain X and you damage the exhaust system? There must be a way to replace it

      The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda.

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.
