I was worried about the check engine light, but this converter kept it off right from the start. The stainless steel construction seems solid, and bolting it up was straightforward.

The welds on this cat look clean and solid, and it slid right into place on my old Chevy without any cutting. Was a bit nervous about fitment, but the universal design truly delivered. Engine purrs and no check engine light so far.

Bolted it on a Sunday afternoon, and the universal fit meant I didn’t have to hack up the piping like with my last one. The check engine light stayed off through a week of commuting, which is exactly what I needed from a federal-compliant unit.
