Thanks doing so still allows for control of the valves via the different settings I assume?

I was very interested in that system, but they could not give me a concrete date on release when I contacted them. It's been "available for preorder" for a long time on their site.

Yup, contacted them via Instagram with no response.

I emailed a few months back and got a response saying I was more than welcome to preorder one. They said the exhaust should be ready by April. Nothing yet. It sucks to see something that seems to be a real game changer take so long to come to market. That black ZL1 they used for a test car is on a few of the Race Proven Motorsports youtube videos getting tuned. It sounds like an absolute beast. I would've gladly bought one of their systems, but couldn't wait forever.

(roughly $100-150 depending on the shops, maybe cheaper if you know someone)



Either way, you have to go after what you like and is within your budget...there will be pros/cons to anything you choose

I’m confused. The video says muffler delete, but in the video someone says he is playing with the valves (I assume NPP).

I've got the same and its definitely more aggressive - I would also say it cures anyone that has GT350 exhaust envy. It obviously sounds different, but gives the car a different attitude. It sounds full on race car when transmission is in PSM - the downshifts are amazing!

That said, the Corsa exhaust is also really good...I just prefer the Borla sound. You can't go wrong either way.

Yup. I got the ATAK with the CF tips. I can still drive around town at reasonable levels as long as I keep my foot out of it. I wanted to hear the car from the outside so a friend of mine with an E92 M3 and I switched. I followed my car with the windows down and between the wind noise and my car I literally never heard his BMW

[headgamez]

Do you have the NPP? I was wondering the sound difference with open vs closed valve in real life. Cant really tell on video.

[BDivine76]

About that...I kind of messed up when ordering and get the version without. In fairness, I didn't specify I wanted them (kind of assumed) and Phastek didn't ask. At the end of the day I'm not too worried as I would leave them open all the time anyway. I just can't leave the house at 6AM because the cold starts are nasty!
