Hey buddy awesome video ! I’m about to put SE headers on the new 6.2 high country I just bought. Where’d you get the gold spark plug boots ?

[@hunterrwiilson]

Thanks man!! Dude that's gonna sound sick! I know you'll enjoy that. But I got my sleeves I believe from Amazon. I was looking for through my orders and I couldn't find it, but I know I got them from there.

[@ahmadali-cs7wk]

Great content!! Are you thinking of putting the stock exhaust back with the 1 7/8?

[@hunterrwiilson]

Thanks man!! I do have plans to attach my, currently dangling, Borla ATAK with the new headers 😏it's going to sound glorious. Stick around!

[@thekingmedina9244]

did you have to tune it or mess with with computer I have a 5.3 sierra 2018

[@hunterrwiilson]

I plan on getting my truck tuned due to further future mods. But just for long tube headers (LTH), I would personally recommend it. Reasons: 1) you're changing the flow of exhaust fumes in which the ECU isn't tuned for, so the truck will run slightly different (not in it's healthiest manner). 2) you're deleting the rear 02 sensors for the CATs so you will have that pesky check engine light, and idk about you but I hate seeing that light lol. 3) if you don't already have a module that turns off the AFM (V4 mode), then you will hear one of the worst noises you've ever heard from a truck engine in its full loudness with LTH

[@emilliocastorena7361]

After the y pipe does it come with the pice that connects to the factory exhaust

[@hunterrwiilson]

No it doesn't. It comes with the same circular type exhaust ending so you can clamp it back up to a stock exhaust or maybe a bolt-on aftermarket exhaust.

[@emilliocastorena7361]

Okay and what did you do with the back o2 sensor

[@hunterrwiilson]

@@emilliocastorena7361 Threw them away, don't need them anymore. They only monitor the catalytic converters

[@emilliocastorena7361]

So just unplug them or leave them hanging?

[@emilliocastorena7361]

And is there a check engine light on ?
