Customer Reviews (4.8 / 5 · 5 reviews)

Robert B. ★★★★★

Installation was straightforward on my STS 4.6L, and the mandrel-bent tubing gave it a nice smooth flow right out of the box. My check engine light has stayed off since, and the engine feels noticeably more responsive at highway speeds.

Sebastian ★★★★★

Was tired of the check engine light flickering on my STS, but this converter's mandrel-bent tubing made installation straightforward and it's been running smooth for two months now. The EPA compliance is a nice bonus too.

Claire D. ★★★★★

Bolted right up to my STS without any modifications needed, and the check engine light has stayed off for two weeks now. The mandrel-bent tubing feels solid compared to the rusted original I pulled off.
