Avery ★★★★★

I was worried about fitment, but this converter dropped right in without any extra modifications needed. The corrosion-resistant finish is a nice touch for long-term durability. Engine runs smooth and no check engine light after a week of driving.

Michael ★★★★★

I got tired of the P0420 code popping up every other week, so I grabbed this one. The mandrel-bent tubing made installation line up perfectly with my factory hangers. It’s been three months and the engine light hasn’t flickered once.

Ellie ★★★★★

Swapped out my old cat and this direct-fit design saved me a trip to the exhaust shop. The mandrel-bent tubing seems to keep the flow smooth, and no check engine light after a week of driving.
