Customer Reviews (4.6 / 5 · 5 reviews)

Avery ★★★★★

The mandrel-bent tubing made installation straightforward, and the check engine light has stayed off for over a month now. Really glad I went with this CARB-compliant option for my California car.

Samuel R. ★★★★★

Had a P0420 code that wouldn't go away, and this converter dropped right in with no extra fabrication needed. The mandrel-bent tubing kept the exhaust flow smooth, and my check engine light has been off for over a week now.

Michael ★★★★★

Noticed an immediate improvement in throttle response after swapping out my old clogged unit, and the mandrel-bent tubing made installation a breeze with my aftermarket exhaust.
