Victoria ★★★★★

Bolted it on this weekend and the inline four finally sounds like it's supposed to—that high-rpm scream is addictive. The titanium's weight savings are obvious the moment you lift it out of the crate, and the fitment was spot-on for my 4RR.

Ava O. ★★★★★

The titanium finish looks incredible against the black frame, and the fitment was perfect with no modifications needed. The sound is intoxicating once you hit 10,000 RPM.

Chloe T. ★★★★★

The weight difference is the first thing you notice, it’s almost scary how light the whole system feels. Bolted it on this weekend and the inline four finally screams like it should, that titanium tone is pure race.
