5.3 Exhaust?

ngmoore17 · May 18, 2017

New to the site and just purchased a 2017 All-Terrain 5.3L. Been thumbing through exhaust threads and just wanted to seek out some opinions. I had an '05 Sierra 1500 previously with dual in-out magnaflows with turn downs in front of passenger rear tire and am looking for this type of sound in my new ride. Any suggestions on what type of system can give me that type of sound? Will try to upload a clip of my '05 (still have it) if needed. I really like the turn down sound as it gives a really deep rumble (not sure how this will translate to the quieter cabin). Any thoughts or insight would help and thanks in advance.

Also, I'd like to know if it is worth it (warranty wise) to not have it dealer installed and just go to my muffler shop? I'd like to keep my warranty intact if at all possible. Anyone ever had/heard of an exhaust voiding the warranty? I've seen the threads about "modifications that directly cause the issue" can void but just am wondering how likely that is to happen. TIA again.

Everyone will have their own opinions on what exhaust sounds good. I have the Carven R muffler and I'm happy with the sound. And I'm certain exhaust work will not void warranty.

Not going to void your warranty. If you are still worried that you will, GM offers GM by Borla exhausts and also Chevy/GMC performance exhausts which are obviously GM warranty safe. But even if you went someone else, you are fine.

Couple to think about. GM Borla has the AFM flapper to cut AFM drone. They have dual behind the tire and then dual straight out the bumper. Lifetime warranty by Borla because they are Borla made for GM.

Chevy/GMC performance. Those are made by Corsa but are GM branded with a GM warranty. They use the quieter muffler (I forgot the name).

Corsa. You have options for mufflers and then the lifetime warranty that you wouldn't get with the GM ones.

Stainless Works. They make some high quality stuff, and are I think cheaper than Corsa. My brother has their stuff all over his Camaro SS and its some top notch quality pieces.

Save your money. Just do a muffler swap. I have the carven tr and I couldn't be happier it's not loud. Just right

Been watching videos of this and it's growing on me. Sounds as close to my old sound as I can find. How is it with the AFM? Did you leave the resonator and flapper or take them off?

Resonator is on. Flapper is off. But I just had afm taken off yesterday. So I'm pulling th4 pen resonator off and putting a mini resonator in place of the oem for a little more sound. You can't even hear the helicopter with pen resonator and I have a regular cab

Cool. Think I am gonna go with the Carven TR and I'll leave the resonator as I think it'll be too loud without. Still undecided on the flapper and probably won't decide until I get it too the shop. Don't know if they've improved in the '17 models enough to leave it or not.
