ZR2 Exhaust

[KDelta]

Update #2. Spoke with John, a rep. at AWE Exhaust. He stated the company is looking toward early September for a release on a system specifically for the ZR2! I'll be waiting and watching. Can't wait for that sound.

I’d also love to see what corsa comes up with

I agree, I've had Corsa on all of my V8 trucks and they have an incredible sound with no drone.

I’ll be putting my spintech muffler on that was on my 6.2L TB. Sounds amazing and fraction of the price of the full systems

Mine didn't have a Borla on it from the factory, and I wasn't going to pay the $1900 for the Borla cat-back system from GM. I did get a Borla Atak muffler for $300 on Amazon and my local muffler shop put it on. OH BOY! what sound! Love it.

 

[Cblaze]

I did the same thing. Sounds great.

Any drone at highway speeds?

 

[Cblaze]

no not at all.

I used the Borla Atak crate muffler #400844

What's a fair price for a local guy to do the install on that? and do they remove the "flap" that restricts flow as well? Sorry, I am not a mechanical guy, so I hope that last question made sense

 

[Cblaze]

Yes I removed the flapper. So they provided the pipe that is needed to make it fit correct, straightened out the tail pipes that GM can't seem to get level, and charged me $140

I ordered this from Amazon and had it installed yesterday. Really like it... it's subdued when cruising but bold when you're getting into the throttle. I see a decline in my gas mileage coming...

When I first drove it, I noticed a "resonance" at about 1700 - 1800 RPM under a light load. It was noticeably louder, but it's not the oscillation noise in the cab that I associate with a "drone". Hope that makes sense.

If you do just a muffler swap, I would suggest cutting all the 3" pipe out and replace it with a 3.5'" muffler and pipe. The factory 6.2 exhaust goes from 3.5" after the y pipe down to 3" just before the flapper, through the muffler and back to 3.5" before the rear y. The GMPP Borla system is all 3.5" right back to the rear y pipe.

I can confirm that my zr2 I purchased on September 9th, came with the Borla exhaust from the Factory.

Was it listed on the window sticker?

It was not factory installed, it was installed by the dealer. No Borla exhaust systems are installed at the factory. It can be ordered with the truck but they are all shipped separate from the truck and installed by the ordering dealer.

yes it was on the window sticker

yes you are correct, the person who ordered the truck back in May of 2022 ordered it with the borla exhaust. I was waiting for mine to arrive when the dealer called me up and said i can have this one and not have to wait another month.

i was listed on window sticker as "Dealer Installed"
