Isabella N. ★★★★★

Finally silenced the dreaded check engine light on my '04 H2 after months of guessing. The direct-fit design matched up perfectly with the existing flange and hangers, making it a straightforward swap. Corrosion resistance on the housing looks solid, so I'm hoping this one outlasts the factory unit.

Joshua ★★★★★

The mandrel-bent tubing made installation surprisingly straightforward, and it’s been a week with no check engine light. My H2’s exhaust note is actually a bit deeper now, which is a nice bonus.

James ★★★★★

I was braced for a headache swapping out the old converter, but this thing bolted right up with zero modifications. The mandrel-bent tubing feels solid, and after a week of highway driving, the exhaust note is still clean with no rattles.
