Julian ★★★★★

The mandrel-bent tubing made installation straightforward on my S500, and I'm relieved the check engine light stayed off after the swap. Fitment was spot-on with no need for extra modifications.

Andrew Z. ★★★★★

I was worried about the check engine light coming back, but this converter fit perfectly on my S500 and the CARB compliance gives me peace of mind. The corrosion-resistant shell feels solid, and it bolted right up without any extra parts needed.

Timothy N. ★★★★★

The mandrel-bent tubing made installation line up perfectly with the existing exhaust. My check engine light stayed off right away, and it feels built to last compared to the old one.
