Ellie R. ★★★★★ Oct 18, 2026

The silencer slides right into place and makes a huge difference in noise level for daily driving, though you still get that aggressive tone when you step on it. Took me about 10 minutes to install, and now my track car is actually pleasant to drive to work.

Carter N. ★★★★★ Oct 13, 2026

Slapped this in before a 200 mile drive and my ears actually stopped ringing at highway speed. Still sounds mean when I get on it, just no longer obnoxious to my neighbors at 7am. Took about two minutes to install.

Harper Z. ★★★★★ Oct 12, 2026

Was worried my track exhaust would be unbearable on the street, but this silencer takes the edge off just enough. Still get that deep tone on cold starts, just without the drone at highway speeds.
