2019 2020 2021 GMC Sierra Denali Muffler Delete Exhaust Mod Truck Pipes 

Any drone noise at highway speeds?

So I've been on the fence about doing this since I bought the truck in 2018... Did it 3 days ago and why did I wait so long... don't hesitate on doing this.

I did this delete on my 2020. Thinking about getting Corsa now. It still sounds muffled because of the resonators.

Give an update if there is drone in the cab.

What's goin on brother. I've apparently been subscribed to your channel for seven years ever since you uploaded a video of changing a doorknob! Haha Anyways, badass truck man. Sounds pretty freakin good.

How's the drone on highway

I finally find a channel about vehicles … in my area 205

Did you delete the resonator as well?

what size pipe did he use to put in place of the muffler?? and would muffler clamps do the same or weld better then clamp??

now you need a range or pulsar,I had to put a range dfm disabler because of the weird drone and i hate when it cut cylinders, pulsar is better and you can adjust things like tire size, top speed, etc. yourself

How did you put the flag on the back window looks cool 😎

a bro o have the identical truck. and did the same thing. after 2 weeks it started throwing codes. did yours

The truck sounds nice , also do you happen to know what size of pipe he put in after cutting the muffler im trying to diy mine

damn what a huge difference!!!!

That sounds good

what happens if you leave the valve in front of muffler

and if it did throw codes how did u fix it

what percentage you got on tint fam

Any fuel economy change?

Oh ya baby! Nice!

Does this affect your warranty?

Nice! If I did that here in California I’d get life in prison

Where you did that I like

Similarly, back in the 1960's colored guys would walk around with a blaring, 3 ft. long boom box on their shoulder.

Get the quad tips

damn only a 100 bucks

after my warranty expire of course before dont do that.

Program out the DOD.

U lifting it I hope
