I'm looking at a GM Performance Cat Back exhaust P/N 23462044 for my 2017 Silverado.

Does anyone know which Corsa muffler is used in GM systems? Sport or Touring or some other GM spec.??

 

Thanks

Has anyone installed one or had one installed ?

How much louder is it inside the cab and at 70 MPH ??

Should be almost zero difference from stock.  My HD had a Corsa system with the sport muffler and at highway cruising, it was actually a tad quieter than stock.  When you were accelerating at any rate you heard the difference.  With the touring muffler you should be stock sound levels and some increase under load and WOT where the touring would provide even more load and WOT.  And when Corsa says no drone, they mean it.

I have it on my 2017 6.2 cruising at 70 same as stock. In cabin 

 

perfect balance of nice sound and no  drone    IMO

At first almost too quiet but after some miles it changes a bit and is perfect

I thought they used a Borla muffler in those. At least my muffler clearly says Borla on it.  I have the GM catback for my 6.2 (installed at the dealer before picking it up) and you can hear it when accelerating buy going highway speeds, you don't even know it is there. I love it and so does the lady. 

 

The cat-back system is P/N: 19303346

 

I also added the chrome black tips that are P/N: 19303348

They have both the Borla and the GM perf system made by Corsa. No flapper valve in the GM PERF / Corsa system

On the gm performance Corsa system, is there something to stop the chopper noise in v4 mode, any pictures if so?

I’ve heard of the GM borla but didn’t know Corsa also made one for GM. I installed Borla ATAK on mines and love it. If you are paying attention you can tell when it’s in v4 vs V8 but it’s not a big deal. It’s bearly noticeable like very little why I said if you are paying attention you will pick up on it. From what borla states the Touring and S-Type don’t drone and the ATAK is very faint in my opinion

I just took delivery of my 18 crew Highcountry 6.2 and had the dealer put the performance exhaust by  Borla on it and love it. Just the right amount of sound. You hear it accelerating but just barely at a steady speed. No drone at all. When you step on it it comes alive. I do a lot of highway driving and a loud or drowning exhaust would of been a deal braker. The Borla has the flapper valve to meet the GM specs.

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
