Just had mine installed today. Notice a rattle, looks like it's hitting the one cross member. Anyone else have this issue?

Other then that how do you like it? Any drone?

YES!!! I just discovered that issue today. Been arguing with the installing dealer. Spent 20 minutes on the phone with Borla. Their tech says its installed improperly and all the clamps need to be loosened and the exhaust rearranged. If that doesn't work than the exhaust was made wrong.

I have dual single side exit and have no rattle on mine. Overall I love it. Not obnoxiously loud and has a low rumble that sounds good when you step on it. Some small drone. I thought the flapper valve would have done a better job. I would still do it again. Great system!

The sound is great, you can hear it but not too overly loud. I'm just pissed off about the rattle, I'm thinking if u bend up the support rod by the crossmember it would not rattle. Going to call the dealership on Monday for the, to look at it.

I haven't had any issues with mine. Borla GM version, installed at the dealer. They let me hang out with the techs..helped some too. Its not what id call loud but you know its there and sounds good when you get on it. Duals out the back. Zero drone in either V8 or V4. Almost as quiet as stock while cruzing. Perfect for me.

I take what I said back after researching what drone is. The exhaust does not resonate throughout the cabin. The sound I hear is just the funky change to V4, but its def coming from the back of the truck. Not noticeable if radio is up.

 

I do love it!

Went back to dealer today. They loosened up the connection after the cat and readjusted it. Gave more room. Also took a heat torch to the bracket right behind the crossmember and bent it up a little bit. No more rattle and plenty of clearence between crossmember and exhaust pipe. Easy fix, I watched them do the whole job.

They just had to rotate my front pipe up and it came off the frame. Borla techs were very helpful too. The service manager offered to install my GM mud flaps for free for all my trouble

Where are you guys purchasing the GM/Borla? Is this a dealer direct piece or aftermarket?

 

Thanks.

I got mine from the dealer. shopchevyparts.com has the best price I have seen, but you need to pay for shipping. My dealer met their price plus shipping.

^I'll never buy borla. I bought a system for my BMW and it was a cheap rigged system. I had a magnaflow on my F250, very good fitment and quality. BMW ended up with a flanged HKS system which was spot on. Right now the only systems that look real nice (IMO) are Magnaflow, AFE and Corsa. All others compromise somewhere.

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
