Just Bought Sierra All Terrain X - Exhaust?

[Sierra_Steve]

Hey guys, I just bought a 2016 Sierra All Terrain X. I live in Canada near Toronto Ontario. I test drove one at a dealer that had the upgraded exhaust, but then another dealer found one with more options I liked so I bought that site unseen. However, when I received the truck on the way home I realized it did not have the upgraded exhaust. Are all of the All Terrain X packages suppose to have this? I see it listed on some websites as part of the package but not listed on others. I currently have the dealer looking into it for me. I would be really disapointed if it is not part of the package in Canada as it was a main feature I liked. I did see the other forum posting on this but it didn`t have a tonne of answers. ANy additional help or ideas would be awesome. Thanks guys!

All Terrain X includes the GM cat back exhaust in the states. In Canada it is optional however, I don't even see WBC listed in the Canada order guide at all...

 

THIS IS FROM THE US ORDER GUIDE

Well shit.....

Go get custom exhaust done. Should be 750$ for fatback duals.

The duals that comes straight the back looks awful. It sticks out to far from the bumper.

Go get custom pipes and have it out the box side.

[Sierra_Steve]

Reall it would only be about $750? I will have to look into that.

Around here catbacks are $750-800 depending on the company. The retail on the oem borla is over 1k.

I did a MBRP full stainless 3" single side and love the way it sounds

I installed 22" magnaflow and full 3.5 tailpipe sounds good no drone even towing

Original intermediate pipe

did you just put 3.5" pipe from muffler back, no resonator and no flapper?

[JeremyW426]

I went with the factory Borla exhaust accessory and I love it. Admittedly pricey though.

So my dealer should have installed a cat back exhaust on my truck??

So is this the one that is suppose to come with the All terrain X Package? Is this a full cat back system? Do you happen to have a part number?

[JeremyW426]

Part number will vary, I'm not sure what comes with the All Terrain X Package but for mine, I went with dual exit put the passenger side on my DC 6'6" bed which is P/N: 19303337. That's the number without tips and its specific for the 5.3L engine. (should be the same number for a 5.3L CC 5'8" bed)

that is correct

4.5" tip

That was from the order guide. It says that if you factory order RPO code WBC that it will be installed at/by the dealer.

(same thing happens with quite a few other options as well)
