That’s the way to go! Much cheaper than the $1500 cat-back and achieves the same results

Love the comparison of stock and new exhaust inside and outside the car.

Sounds good bro I’m undecided on my 19Sierra till I saw this video lol

That was a well made review. Thank you!

i put Borla Pro XS on everything. Great video

Very well made video thanks for sharing!

Just did this on my 21. Hardly noticeable unless it’s a cold start, I tapped up the resonators on the exhaust pipes and now it sounded like what a borla should!

I did this set up on my 2020 silverado RST 5.3L on Friday. It was just a muffler swap (with flapper valve cut out). At first i was disappointed wiht the sound. The cold crank was the only part that sounded like I had a new muffler. On Saturday, I used high temp aluminum tape and taped all the resonator screens (all 6). It now sounds what i expected it to sound like.

Badass growl

Good video

Did you leave the resonators on ? , sounds good . Cheers

How bad does it drone on the highway? Also did you leave the resonator on?

Did you cut out the flapper on the exhaust too when you installed the muffler?

I love my truck

Going with a single 4 in dbx flomaster

Sounds good, but it sounds even better without the cats

After having the exhaust for a year now are you still happy with it? I am looking at putting some thing on my 2019 Silverado also, just want something slightly louder than stock, would you recommend this? My other option was a borla touring catback, but this would be about $1000 less.

The stock pipe is 2.75”, did you get the 3” Borla? How did you make that fit? Just used the welds as a reducer?

@EightTwoFive_Racing

Did the 3” Borla and added some 3” pipe and welded into place over the 2.75

Did you consider adding cold air intake? It sounds awesome with that borla

Bro thank you so much for this video. I wanted to do this because it’s simple and gives the truck the right tone. Not too loud but let’s you know you have a V8. Did you remove the flapper valve also? I’m ordering this muffler now!!!

Sound is Great! I would consider the Pro XS if i wasn't leasing my 2019 because it is the most practical option cost wise. I just really don't want to cut into the factory exhaust if you do end up trading it up at the end of the term. i have been trying to decide between the Full catback systems in touring and S type. If you had to compare the pro xs to them both, which would you say the sound is closer to? not sure i want to be as loud as the s Type but, really dont know if the touring is going to satisfy.

So true . I havent done an exhuast but I put kilmat in the hole truck and quilt backing. Now I dont have to turn the radio when I'm on the hwy or hear the gravel in my driveway. There is literally no sound deadening in the roof and back wall and pillars. I took me about 20 hrs to take all the trim out the truck in a crew cab cut and roll the sound deadening material and put it back. It is well worth it.
