2019 5.3 on 35s. muffler delete pipe, flapper (in front of the muffler) is locked open, S&B CAI. Cold starts are aggressive and loud but eases down quickly. I don't notice much if it's there. I went the cheapest route first to see if it was too much. I stuck with my set-uphow bad is the drone with the muffler delete pipe?
Borla S-type cat back, loud cold start, good rumble when accelerating, zero drone, and quiet as stock when cruising on the highway. It comes with black quad tips so you can get rid or the chrome usb port tips.Hey ya’ll. I bought a 2022 TB 5.3L and absolutely hate this stock exhaust as all of us do. I still have a bit of factory warranty left in addition to an extended warranty I purchased, so I’m not sure how this works with respect to doing cat back, delete’s, etc. this is my daily driver. I like the throaty sound but no drone or severe droning, but don’t want to be aggressive. Can anyone tell me what to avoid? Thanks ya’ll
Hey. Any drone in cabin at cruising speed?AFE Apollo GT muffler, $236 direct but should be a little cheaper on other sites. Gives it a nice throaty tone, not overly loud and I'm thoroughly pleased with it. I cut the flapper off and barely had enough length, so if you go this route cut off no more than you have to. (extension pipe is included) Not a super snug fit, so you have to really tighten down the clamps. You'll probably knock off about 10 lbs of weight too as the factory muffler is much larger.
Well this ought to be interesting… the new muffler came today and will be going on Thursday morning. I’ll be keeping the “active” valve on one of the outlet pipes. Hope to report back with pics and a video or two.I have the 6.2/active exhaust on my ‘24 and I’ll be doing a muffler swap in the near future. I’m hearing/reading that AWE is the only system that has valve simulator figured out to not throw codes, and I’m not prepared to drop $2k on a full system, so I’m planning on a single in, dual out, replacement and reusing the active valve. We’ll see how it works out.
I’m interested to hear how it sounds. I need to post a video of my spintech 9000xl. I was initially underwhelmed but now have 3-400 miles on it and think it sounds great. I’d love to compare. Enjoy!I didn't want mine too loud, I had magna flow on my '03 Silverado SS with 6.0l. that was nice and loud no drone. But my 21 6.2 I don't want as loud, so called Holley and they suggested the flow master delta flow 50. Sounds nice and for a baffle muffler no drone so far(3 weeks). Borla won't sell muffler only, this was my first choice
I'll do another start up vid rn. First one was to longI’m interested to hear how it sounds. I need to post a video of my spintech 9000xl. I was initially underwhelmed but now have 3-400 miles on it and think it sounds great. I’d love to compare. Enjoy!
Well I guess I can't share a video on here. Says they are all to big. Can't adjust settings on phone. Kept making shorter videos, but nothing. SorryI’m interested to hear how it sounds.
