I Prototyped an AWE SwitchPath Exhaust on my ZLE!
Like the title says... I Prototyped the AWE SwitchPath Axle-Back Exhaust system on my ZLE so I could have a true 3" ID (Inside Diameter) pipe, unrestricted from the ARH headers to the tips, no cats. The NPP Muffler was good for being quiet but the tin sound just had to go... along with the restriction of flow.
I have seen dozens of ZLEs at tracks and many with different brands of axle-back systems, but nothing on the market has that deep 2-Chamber Flowmaster sound anymore. Diving deeper into the NPP Valve systems, the AWE setups use a stronger Escalade-V 3" Spring Valve similar to the Hellcat and Mercedes AMG valves and everything on the market for the 6th-Gen uses the smaller un-sprung valves to operate the OEM NPP Actuators. So now you have the back-story on this system... I reached out to AWE and came to an agreement to invest my time & money to prototype the system, cherry-picking their current parts to build the system on my car. If there is enough interest in building this setup, they will kit the system for us. I have not tracked the car since completing the install as there is too much going on at the shop, but I shot some clips on the road trip to Hendrick Motorsports in Charlotte from Darlington, SC as well as a cold start in the video below. If you like what you hear, leave a comment in the video as I have shared the analytics with AWE Tuning as I have never heard a ZLE sound as amazing as this one. |

I run a chambered dual in dual out Black Widow Venom 250 muffler in place of an X pipe at the tunnel, into a Borla X and then run it into a Corsa Xtreme cat back set up. It actually sounds pretty darn good because of the initial chambered set up before any of the other piping design and mufflers. Of course ears other than mine that do not have tinnitus will probably be a better judge as to whether or not it has a tinny sound to it, but the AWE switchback set up that you got fabbed up in your photos looks really sweet too. Depending on time and ease of switching over, I may actually be interested in something like this myself, but as of right now I like the way my set up sounds.

Sweet! Sent an email. I’ve been waiting for an AWE exhaust with NPP since I got my car…

Very cool product, and nice video Dave! Would love to hear it in person some day...
Can you share the weight of the kit vs. the OEM suitcase?

Are those small resonators I see at the axle? I really like the look of that system.

I would be interested in purchasing this as well. Not sure if this has been asked/answered yet but does the valves utilize the stock plug/harness that came on the ZL1? They look pretty far back on the exhaust and I'm not sure the harness would reach that far.

I'm potentially interested, too.
It would be very-very nice not to have to ditch the expensive actuators that came with the car (MSRP $377 each) and buy new, larger CT5-V ones that are probably even more expensive.
