[@joshc9846]

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.

[@leamangriffin]

Heck yeah man! Thanks!

[@kayjayhilfiger]

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

[@salvadortapia3851]

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

[@torah57mitch]

That sounds good

[@benjohnson1440]

Oh ya baby! Nice!

[@raulrios5054]

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

[@kiddt1999]

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

[@theodorejuett374]

Give an update if there is drone in the cab.

[@Pyrojodge1]

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.

Any drone at highway speeds?

[@bryceseale5824]

Did you delete the resonator as well?

[@johnporter5177]

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

[@johnporter5177]

what happens if you leave the valve in front of muffler

[@briankilichowski235]

How's the drone on highway

[@MeatHeadMalz]

Any fuel economy change?

[@johnporter5177]

and if it did throw codes how did u fix it

[@heybucko3956]

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

[@kiddt1999]

Just installed the Pulsar. Badass.

[@HarleyFatBoyJr]

what percentage you got on tint fam

[@jakemilne2385]

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??

[@terryhook5518]

Get the quad tips

Does this affect your warranty?

[@Lifehackz137]

Only if wat ever messes up is related to the exhaust I just bought a 2021 gmc 5.3 sle and they told me this

[@tommy-jy5ig]

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

[@user-zt6bt8dp2c]

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

[@wilfridomontesdeoca7043]

Where you did that I like

[@wilfridomontesdeoca7043]

Can you give me the address please

[@HarleyFatBoyJr]

damn only a 100 bucks

[@user-qw7od9ud6m]

after my warranty expire of course before dont do that.

[@diydozier3205]

Program out the DOD.

[@leamangriffin]

I wish it was that simple. On these you have to send the ecu to hp tuners to have it unlocked.

[@diydozier3205]

@@leamangriffin pulsar LT. It's what you need.

[@leamangriffin]

Yeah i remember that from my 2019 silverado. But i dont want to leave it plugged in to the obd port the whole time.
