GM performance 23462043 6.2 Exhaust Kit Installed :)

[CDNSS]

2017 AllTerrain CC 6.2 took delivery of my factory order on Monday part of my deal was this kit ( not installed, box in bed when I got truck ) have 60 miles on it ....

 

Installed a 1.5 level kit and this exhaust tonite quality item for sure fit perfect took 2 of us maybe 30 minutes to install on a lift single 4" tip side exit

 

AFAIK this kit made by Corsa no flapper like the Borla just one huge 28" oval muffler no resonator NO V4 helicopter sound on drive home from shop V4 was hardly different from V8 most would never know

For me is exactly what I wanted .........my 2010 5.3 had headers no cats and Magnaflow cat back sounded great but after a while just too loud at cruise especially when towing V4 was not a problem

 

This is not a loud exhaust alot would not like it it is quieter than the Borla touring ...nice rumble at idle but you barely hear it in cab at idle at WOT again not load but a deep roar my truck still has stock air box on it so I would expect an aftermarket intake would be louder than the exhaust

 

I assume this is the Exhaust that comes on the ALL Terrain X but in the smaller diameter for the 5.3

 

the 6.2 kit comes with an ANC recalibration code so you take to dealer they provide code to GM and they get a recalibrate update for the ANC to work with this exhaust ......

 

Overalll very pleased my days of load exhaust are over but the factory 6.2 exhaust is pitiful this is perfect for me I expect it will get a bit loader as I put some miles on it

Great write-up and confirms that ANC is indeed modified/changed by the dealer.

Tks yes I was confused on that could not find any info on how that worked now I know ........ IMO this what a 6.2 factory exhaust should sound like I can see it would be awesome with headers and still not super loud I would call this a "seniors or gentlemans " hot rod exhaust

So does this exhaust have or dosen't have anything for when it's in v4 mode to stop the helicopter noise, and is this kit any different then the kit offered from Corsa

I am wondering how loud this exhaust is. I recently had a magnaflo 12909 muffler installed on my 2017 Sierra and I think its to loud. I must be getting old but I want something louder than stock but not so loud that I can hear it in the cab. I thought the factory exhaust on my 2011 6.2 was perfect.

I'm in same boat. Factory is too damn quiet. I only have 1800 miles on my truck so maybe it will get a bit louder with more miles? 

 

A GMT 900 6.2 factory exhaust sounded just right!

 

Too bad we can't turn off the Noise canceling since that may cancel out some exhaust tone.

I agree that the stock exhaust is to quiet, I can't hear it start in my driveway when I remote start it. I went with the 12909 because everyone said it was a little louder than stock but to my old man ears its alot louder. If this gm performance exhaust is close to the sound from my old truck I may go for it. By the way, the factory exhaust doesn't get any louder, I have 11k on my truck and still too quiet.

I turned off the noise cancelling for my stereo upgrade by cutting the crankshaft replicating sensor at the back passenger side door...Sub would get out of phase and make a horrible noise....I removed my flapper, resonator and OEM muffler. Replaced with 12909 about a year ago. Happy with sound in and out of the cab now...I missed my 2008 Denali 6 2 L sound as well.

Hi Bill, Did you buy your exhaust through a Canadian GM dealer? Or where? How much in Canadian Pesos? hahaha

[Crobinson16]

Would you happen to have any sound clips of this exhaust. In cab and or outside. Thanks
