Sounds so much better than stock

[@chs9627]

Hell yea, they want you to drop that 2500 extra lol

[@jackieclan815]

One question is the sound louder than the default or about the same

[@akendon7260]

Keep in mind latest production of AT4X, I believe from January 2023, has option for the visible square dual exhaust tips as seen in your video. The tucked in option is still available for those who want to do more offroading with it.

[@cgerardo10]

What type is it touring, s-type or atak?

[@rmhtxrxl]

How does it sound in the cab?

[@RichardRodriguez-ke1vl]

Flowmaster Super 10 sounds better on my 23 Sierra Denali Ultimate. Then the dealer option and performance is about equal. But I paid much less then if I went with the dealer option. $260 total for muffler and install.

[@ericmcnair3569]

Is this available and would it sound the same in the video for a diesel gmc sierra denali?

[@bradwalker8544]

I know this is a Borla system technically. But which system is it ? Touring , s type?

[@AlejandroMartinez-ug3qr]

That’s what I have wondered as I can’t find anything but after reviewing so many videos it’s sounds more towards the s type. Touring always sounds barely over stock.

[@user-qy8il6yz2p]

I have this exhaust on my 2021 AT4 , can i get the quad tips to go along with this exhaust in carbon fiber?

[@pain4profit267]

So does the kit pipes just go up next to the rectangle exit port ?

[@svtkilla39]

Isn't this just a repackaged Borla catback?

[@scottinak]

Yes!

[@theoverlook5976]

One question. Is it worth it?

[@texasfan8892]

In terms of sound, that’s all subjective. Some people might want something far more aggressive, such as the ATAK series, the AWE OFG exhaust, muffler delete, etc. In terms of quality, it’s a Borla system and the quality is second to none. Full 304 stainless steel that will last longer than the truck itself. In terms of financial terms, since you can order it with the truck, it’ll be rolled into the monthly payments, as opposed to having shell out a bunch of money at once for an exhaust system afterwards. The biggest thing, however, is that because it’s installed by the dealer, it’s backed by the manufacturer and will be serviced by the dealer for as long as the warranty is in effect. But in the end, it’s all personal preference.

Will replacing my exhaust system turn on my check engine light?

[@pchivers8888]

No

[@D_Carrillo08]
