I have a GM borla single side exit and I like it, has the flapper so no AFM chop, also no drone. It’s not super loud, but sounds good on a cold start and when you get on it. Otherwise everyone has good things to say about Corsa. I also like magnaflow, but not sure about a single side exit option, I had dual rear exit on my 2011.

I need to do some research on this AFM Chop to see what its like on and exhaust without the flapper. Hows the price of the GM borla compared to the normal borla exhaust?

I found one lightly used and paid around $800, the black tips look awesome. I wanna say with the tips they’re around $1300 new. For sound reference, the GM kit is the same level of sound as the touring version of borlas regular exhaust systems. I’m sure it’s a bit more expensive than the normal borla, but If you don’t plan on getting something to remove the AFM (tune or range device), you will most likely have some chop when it goes into V4. It was pretty annoying on my 2011, meant to tune it out, but never got around to it.

I would suggest just cutting out the muffler.  Easy and cheap, and you'll get the sound you want.  Leave the resonator to reduce drone.

 

I took out the muffler and resonator, which would be too loud for what you are wanting but it sounds great.  Here's my truck:

Did you cut the flapper valve thing out too?

Yep that came out too.  the exhaust was cut after the 3rd cat and from there , added a y-pipe to make it dual exhaust.

Check out my thread on here "2015 6.2 Sierra with Black Widow Venom 250" I give details about the V4 chop and drone.

 

Maybe the Venom 300 would be what you are looking for, it's a bigger version of the 250 so it'll be a bit tamer.

Here's another video, some driving towards the end of V4 mode from inside the cab:

I just purchased the single side exit SLP, but I haven’t installed it yet. The clips on the net sound good, and it seems pretty quiet during cruising. We’ll see, and I’ll make sure to post when I install it.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      By SteveP45 · Posted

      Idler Pulley… from what I understand GM and Chevy trucks no longer have an idler pulley.. they stretch belts for both belts… I had mine replaced by my local mechanic last year on my Chevy Silverado 5.3 z71 LT.   They have discontinued using them on 2019 through 2026 as of a Google search.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      By Fatboy2V-rod · Posted

      Good morning! I have a whirring sound coming from the engine or transmission area when driving w/o towing when I accelerate at 1100 rpm’s. That’s how it started. Yesterday it was more obvious while towing a U-Haul even when not accelerating at 70 mph. I could see where it may have been possibly shifting gears due to a slight grade and the intermittent rpm changes as the transmission was possibly lowering the gear down. It was making the sound multiple times but it is not constant. I replaced the serpentine belt and idler pulley but no change. It only does it when I’m driving. No noise accelerating while in park. Just started @ 53,000 miles. It’s not always there though. Unfortunately, I feel it may be transmission related. Any thoughts or knowledge about the 2022 tranny that anyone can share. I have 2500 miles left on my p-train warranty. Thanks to all for any help!

      RAIN. It's dumping buckets. We needed it. What a welcome change...sitting here listening to it pour with my office window open.   Ok, not too much. It's not even September yet, we're not finished with summer yet....

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      If you have actually done it, there must be some secret tool or method of accessing the hidden bolt head that both manifold connections have. Two of the three bolt heads are staring at you in the face from below but the third one is covered by shielding and as far as I know only accessed by removing part of the fender well lining to gain access to it and even then its awful to access or from what I had seen of someone fighting with it on a video.    There is a reason why even mechanics that deal with the awkward or risky business of undoing the exhaust at the manifolds have done the same method others are doing with these L8T by flexing the exhaust if need be or just able to slip the pan out as I did without needing to touch hardware or pry on the exhaust. By rights the two seals should be replace when those joints are cracked loose as well.

      Actually it was a lot more controlled then I thought it might be and that isn't actually when I spilled some oil. I had thought prior of rounding up a couple of longer bolts with the same thread to swap out for a couple of the front edge pan bolts and then leaving one bolt left in the back but loosened off and then using a suction device to remove most of the fluid, that certainly would have worked and while I do have a couple of different devices I could have used to suck the fluid, now having done the job once I wouldn't even bother. I had thought of buying one of those pressurized vessels to suck or new fluid in and would if I was doing a job like this on a few vehicles but with one vehicle I just didn't bother and I have pail pumps as well I could have used assuming the hose end would fit into that less than roomy space but being such a thin fluid it pumped well with a quart type pump and just kept the hose into the trans and kept swapping containers and repeat.    What I would change to the method I did though was first jack up just the rear of the truck to put on jack stands to allow more oil to come out of the check plug on the front of the pan ( and as I did, I made sure to put that drain plug back in finger tight ) then follow through by putting the front on jack stands. Also that I would have used a larger sized drain pan in the sense of covering an area wider/longer beyond the transmission but I didn't have one and saw someone else on a youtube video using a masonry mud mixing tub and bought one at a hardware store to use in the future. The main oopsy  I did and why I spilled some oil was all my fault as I neglected to follow my own plan, I should have let down the pan as I did to drain out the front of it as much as would come out but then scooped out the remainder of the oil with the Dixie cup I had sitting there just for that purpose as by that point there is enough room to reach right into the front of the pan and just bail it out basically.
