Customer Reviews (4.8 / 5 · 5 reviews)

Sofia Z. ★★★★★

The installation was straightforward since it bolted right up to the existing hangers, and the mandrel-bent tubing definitely improved the exhaust flow. My check engine light has stayed off for two weeks now, so the CARB compliance is working as advertised.

Julian O. ★★★★★

Pulled my old Mustang into the garage with the check engine light glowing, and after swapping in this converter the light stayed off and the exhaust note smoothed out noticeably. The mandrel-bent tubing made for a clean flow, and the direct-fit design had me buttoned up in under two hours.

Chloe ★★★★★

The install was straightforward since everything bolted up exactly where it should, and the CARB compliance sticker gave me peace of mind for California smog. Check engine light stayed off after a week of driving, which is all I really wanted.
