Victoria H. ★★★★★

The mandrel-bent tubing made installation straightforward, and my check engine light is finally off after dealing with that P0420 code. The direct-fit design lined up perfectly with the existing mounts, which saved me an hour of hassle under the car.

Sophia D. ★★★★★

Dealing with a P0420 code was driving me crazy, and this converter shut the light off for good. The direct-fit design meant no cutting or welding, which made the whole swap a breeze.

Eli R. ★★★★★

The mandrel-bent tubing made installation a breeze, and the check engine light hasn’t come back on since I bolted it up. Fits perfectly on my H3T and the exhaust note is a bit deeper now too.
