2016 GMC Sierra All Terrain X Exhaust

Mtyv23 · June 28, 2018

I purchased a new 2016 gmc all terrain x in October 2016. I was watching a few YouTube videos of other guys all terrain X's and noticed a different exhaust. After looking at mine closer I think my dealership left the stock exhaust on instead of the upgraded performance exhaust.

It looks like the stock exhaust is part #20757703 and the performance is 23442234. Can anyone verify? Any thoughts on how to approach this with the dealership since it's almost been two years since I bought the truck?

That is definitely stock.
I’m surprised they didn’t try to cover it with the tip it is supposed to come with.

The best encounter I had at a dealership, is when I bought the truck with no loan from GM... I brought back for a paint “bubble” that “got passed QC” and got dragged around for two weeks... there’s no good approach to dealing with a dealership... just go it, be firm and do what you gota do. I will scan around and see if I can find a part number on my exhaust so you can atleast show them what’s up. I will also dig up my build sheet and send you a pic of that...
hold off on the dealership until you have all the info you need.

I would appreciate it. There's an all Terrain X discount for $750 at the end of my build sheet with no explanation. Not sure if that would have anything to do with it. Hollywoodsle looked up my VIN and said whatever the performance exhaust is, wasn't a dealer installed option, its showing that my truck does have it.
