Leo F. ★★★★★

I was a bit worried about the fitment on my '09 CTS, but this converter bolted right up without any modifications. The corrosion-resistant stainless steel case gives me peace of mind for the long haul.

Andrew J. ★★★★★

The mandrel-bent tubing on this converter made installation line up perfectly with the factory hangers, no modifications needed. It’s been a week and the car feels responsive again, plus that CARB compliance sticker gave me peace of mind for smog check.

Emma C. ★★★★★

My check engine light turned off immediately after installing this on my 2010 STS. The mandrel-bent tubing made for a clean fit without having to modify anything.
