No. Those exhaust kits with those part numbers were new for 2016 year, but will fit 2014+. There are a completely different set of part numbers for the Borla by GM exhaust. The 8 numbers I posted on the front page, the Corsa made ones, are Double and Crew Cab only. The GM/Borla systems cover all the cab configurations and have two different exit designs (dual split under the bumper, and dual out of the passenger side). The GM Performance system (the Corsa ones) are only single pipe with passenger side exit.

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.

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.

 

 

Could you post a picture of the new muffler? I just purchased my All Terrain on monday and noticed that the muffler on it it huge! just want to compare to see if I have the right exhaust. Or perhaps I need to check with the dealer on this swap!

Yep - to clarify it was an exhaust system after all. The reference to muffler was just how the salesman described it. Next thing I saw my truck on a lift with my entire exhaust system on the floor.

 

at this point in the thread it would seem helpful to others too. I'll post pics of any stamps or rollmarks, the tip, and if it has a flapper or not, etc. I get comments all the time and honestly don't know if I have a corsa or borla at this point but will look into it further.

Damn, poor bastards who paid $5k for a performance off road package that can be had for $900 of existing aftermarket parts. Smh

 

I think as a package on the car I managed more of a discount (jury still out) then I would have part by part retail. My preference is OEM so the criteria is different. I got 20% discount from GMC + $2,500 from dealer on the truck. The X package is discounted on sticker as well when combined with All Terrain + All Terrain Premium/Plus + All Terrain X. Have to check this.

 

Do like the rubber mats that cover the door sill and end to end carpet.

 

All Terrain X Package (MSRP)

- Assist Steps - Off-Road = $795.00

- Performance Exhaust = $1,195.00

- Rear Floor Liners (edge to edge) - Premium All-Weather = $80.00

- Front Floor Liners (edge to edge) - Premium All-Weather = $110.00

- Sport bar = $895

- Wheels? count them not sure.

- X package discount on sticker (have to check but around $1200ish)

 

Didn't have to install anything - even though I enjoy that, under warranty @ GMC, warranty void BS for the uninformed services reps.

Happy this route, was also happy buying aftermarket too piece by piece before -its just where im at personally these days.

 

Floor mats were a bonus - never knew they existed until I saw the truck in person.

aftermarkets ones in my amazon cart but didn't need them anymore (they totaled $250ish)

Could your do me a solid, and crawl under the truck and just take pictures of the whole thing? like cats all the way back? perhaps a measurement of how long the muffler is too?

 

My muffler is the size of a small radiator!! SERIOUSLY ITS 28+" long

 

Here are pics of my exhaust, sorry the site is flipping my photos however it pleases

I really like this thread. So do you have the helicopter sound in v4 with this exhaust. I can't make my mind up between this and the Borla. Thank you!

I notice it looks like the single exit tip clamps on. Makes me wonder if one could put the dual side exit corsa tips on that exhaust.

I dont have the helicopter sound on the truck. but then again it only has 200 miles. I called the dealer and asked about the performance exhaust and told them that I think mine is just stock. I emailed the pictures to the service guy to see what he thought. his exhaust guy is not in till monday :(

You would have the helicopter sound at any mileage if the flapper is removed. Check and see if you have the muffler, followed by the flapper, and then the resonator. If you do than you have the stock exhaust.

No flappers that I can see. I dont see how this is called a performance exhaust when the muffler is the size of a water heater.

Thank you for the pics. Yeah you have the performance exhaust for sure. That muffler is a straight through design that is Corsa's touring muffler iirc. The size is probably used to keep the sound down while not hurting performance.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
