Riley ★★★★★

Fifteen minutes after bolting this in, the CEL shut off and hasn't come back in a week—the mandrel-bent tubing made lining it up with the stock hangers a breeze. Corrosion resistance is a plus since I'm in the rust belt.

Zoe ★★★★★

That check engine light is finally off after installing this converter on my '11 CTS—the mandrel-bent tubing made the swap straightforward. The CARB compliance was exactly what I needed for California smog, and the whole thing feels solidly built.

Emily A. ★★★★★

Smog test was due in two weeks and I was dreading it, but after swapping this in the light stayed off and it passed with zero drama. The mandrel-bent tubing made for a clean, hassle-free fit against the factory pipes.
