Chris S –
With the valves closed, the exhaust sounds nearly identical to stock—perfect for keeping things quiet when needed. But open the valves, and it transforms entirely. The sound is phenomenal: aggressive, refined, and reminiscent of a GT3 RS.
The valve remote can also be programmed to the factory Homelink, which adds a great layer of convenience.
I get compliments every time I drive. Even friends with serious performance cars—a C8 Z06 and a McLaren 720S—have commented on how incredible it sounds.
Another huge plus: with the valves open and cruising at 2,000–2,500 RPM, there’s no drone at all. Just clean, powerful sound when you want it, and near silence when you don’t.
Highly recommended—this exhaust completely transforms the driving experience.
