Amelia N. ★★★★★

Installation was straightforward with the mandrel-bent tubing lining up perfectly with the factory hangers, and it cleared up the exhaust leak I had for months. The CARB compliance gives me peace of mind come smog check time, and the stainless steel build feels solid enough to last years.

Sofia ★★★★★

The check engine light finally went off after I swapped in this converter, and the mandrel-bent tubing made for a straightforward install on my F-150. Corrosion resistance is a big plus since I'm near the coast, and it's been running clean for two weeks straight.

Evelyn ★★★★★

Took me a weekend to bolt on, but the mandrel-bent tubing made the fit way easier than wrestling with that old rusted unit. Carb compliance means I don't have to worry about smog check drama for my 5.4L, and the check engine light hasn't flickered once since.
