I was worried about passing California smog, but this converter paired perfectly with my Civic’s stock exhaust—no CEL and no hassle.

The mandrel-bent tubing is noticeable — I felt a slight power gain on the highway. Bolted right up to my 2013 Civic with no extra parts needed, and the check engine light hasn't come back on after a week of driving.

It was a bit of a DIY project, but the direct-fit design saved me a trip to the shop on my 2006 Civic. The check engine light stayed off from the first start, and the mandrel-bent tubing looks solid underneath.
