Customer Reviews (4.6 / 5 · 5 reviews)

Scarlett ★★★★★

Bolted right up to my S550 without any cutting or welding needed, and the check engine light stayed off after install. Car runs smooth and quiet with no exhaust smell inside the cabin.

William ★★★★★

The mandrel-bent tubing made installation a breeze, and it fit perfectly under my S550 without any modifications needed. I've been driving for about 500 miles now with the check engine light staying off, exactly what I was hoping for.

Adam K. ★★★★★

Mandrel-bent tubing meant zero fuss during installation, and the EPA compliance gave me peace of mind for emissions testing. After a few hundred miles, everything still runs smooth and quiet.
