2024 GM Factory 6.2 Active Exhaust

[Dickie Dunkelberger]

Looking at a recent post from Autoblog for the 2024 Silverado updates, pretty intrigued about a mention for a factory active exhaust system. Wonder if this could be added to our existing trucks.

"The last change is the addition of a new Active Exhaust for Silverados with the 6.2-liter V8. This is a valved exhaust that opens up in Sport mode for a more aggressive note."

I would think it would not be easy with all the electronics and dealer activation stuff...

But, I am not that smart so... There might be some company out there that has a programmer figure out how to retrofit onto earlier models...

May be waiting a while to have someone crack this new GM electrical architecture. Hoping it can be done, cause seemingly the dealers won't/can't activate anything that was not on the original build anymore (talking about sport mode here, as with other features).

Perhaps this will spur some innovation from the aftermarket. Hard to believe a company like borla or corsa has not figured out how to have a bolt on valved exhaust system as an option.

Isn't "Active" the industry term for artificial engine sounds being played through the stereo system?

I'll stick with my Borla Exhaust. Same thing and guess what? I don't need a computer to run it! Just my $0.02 worth!

NO. The Camaro and Corvette have active exhaust options and they have an electronic valve in the exhaust that opens up to allow for more straight through exhaust. Chargers and Challengers have this as does the Mustang.

I had switch activated electric “cutouts” on my old Corvette exhaust. Pretty simple for any exhaust shop to fabricate.

I was just reading up on this myself. Pretty cool feature! And come to think of it, it would be the only time that sport mode actually adds power. Small power, but still. Before, it just made it feel more powerful with a more sensitive throttle and gears hanging on longer. That would be a pretty cool sport mode, because now it even sounds faster.

It’s just a factory electric cutout/bypass that bypasses the muffler. You can get one for about $150 and open and close it at will for a factory stock sound or a race car-like dumped exhaust.

True. But to have it configured to activate with Sport Mode is actually pretty cool. That would be a sport mode that I would use more often. My truck already has aftermarket exhaust and my tune makes it so that the throttle is sensitive enough, so Sport mode almost makes it irritatingly sensitive lol.

I was going to add an aftermarket cutout to my 6.2. Called my muffler shop and he said it was a bad idea. He said he has taken off as many as he has installed. Said the flappers start to rattle and the motor is not in a sealed housing so they go to crap very soon and stop working. I looked into trying to find a high-quality unit as in the Corvette C8. I found the manufacturer of the one GM uses in the Vette is made by a company called Tenneco. I can not find a retail outlet for the part, however. In my research, I got the pleasure of listening to a C8 6.2 yesterday. Damn, that was nice. Sure wish there was an answer to this but so far I have come up empty. Summit Racing still has some of the flow master mufflers that came with the kit installed but only for a 5.3. Flow Master has discontinued them as far as I can tell.

I had electric cutouts on my C5 Corvette from quicktimeperformance.com
They worked with no problems in the 5 yrs I had the car. Granted my Vette was only driven on dry pavement in San Diego so the cutouts were never in a harsh environment.
This was recorded about 17 yrs ago on
an iphone. Sounded better in person depending on if you ask me or my wife.

 

[HammerBoss]

That sounds great, so you never experienced any of the rattling of the flapper?

 

[Jmzvet]

I never had any rattling of anything that I noticed.

Some of the roads in San Diego are so bad that the only rattling you'd hear was your coins and keys
