Exhaust

[SteelBoss6.2]

I did next day air.. only $10 more than the standard shipping lol

Your welcome. I bought two today, my buddy wanted one for his AT4. I was haunting these guys for months about getting DFM delete and was pleasantly suprised with all the additional features. Cant wait, so stoked. You know of anyone who may want my pedal commander? Probably won't need it once this things installed

New to the forum. Got my 2021 TB 6.2 10 speed about a month ago. Put 40 series with flapper delete and DFM sound was terrible. Switched to more mellow sound or Borla cat back touring with Cold Air Inductions intake and Love the low tone growl that wakes up when you hit the pedal! Also added Wesdon exhaust tips. On the DFM, The Pulsar LT gives you the option to shut off as well as 7 other options you can modify like setting speed limiter. Not certified by Holley yet for 2021 but American Trucks willing to refund me if I hit issues. Its expensive but worth the money to me to get rid of DFM! Should be here by Friday. I will let ya know how it works

I’ll be getting Gibson exhaust for mine, had it on my 6.2L high country and now I’ll never use another brand, have it straight piped and flapper out at the moment and Range AFM/DFM disabler. Very little drone now. And the S&B CAI helped with that majorly.

I’m looking at an after market exhaust. I have always run 40 series Flowmasters but with this truck being a lot quieter, I’m thinking 10 series or straight pipe. Any thoughts out there?

Have a ‘21 TB 5.3 with AWE OFG Exhaust. couldn’t be happier. Cold starts are amazing. Super quiet in the cab when going down the highway and no droning but the second ya goose it it’s very loud. My buddy deleted his Denali and it’s louder than his truck.
