Benjamin ★★★★★ Aug 17, 2026

That weight reduction is immediately noticeable in the corners, and the F1-style note it unleashes is pure madness above 7k rpm. My neighbors hate me now, but honestly, that's exactly what I signed up for.

Sebastian P. ★★★★★ Aug 16, 2026

Took the GT3 out for a proper canyon run after bolting this on, and the weight savings are immediately noticeable in the corners. The F1-style note is exactly the aggressive soundtrack I was after, and it's somehow even better at full throttle.

Scarlett ★★★★★ Jul 24, 2026

Installed this over the weekend and the weight savings were immediately noticeable when I picked up the box. The F1-style exhaust note it gives the GT3 is absolutely intoxicating, especially in the upper RPM range.
