Olivia K. ★★★★★

I was worried about passing smog with my IS300, but this converter fired up and the check engine light stayed off immediately. The mandrel-bent tubing looks like quality work and the fit was perfect with no extra adapters needed.

Harper ★★★★★

Bolted right up without any cutting or welding, and the mandrel-bent tubing keeps the exhaust note clean. The check engine light stayed off through smog, which was the whole reason I swapped it.

Benjamin ★★★★★

I was skeptical about the direct-fit claim, but it bolted right up to my IS300’s exhaust without any cutting or welding. The check engine light stayed off after install, which was my main worry, and the idle feels smoother than with the old clogged unit.
