Henry ★★★★★

My 2007 GS430's check engine light had been bugging me for months—this converter fixed it instantly. The mandrel-bent tubing made installation a breeze compared to the original.

Joshua W. ★★★★★

Installed this on my 2007 SC430 and the fit was absolutely perfect, no modifications needed. The mandrel-bent tubing looks quality and the check engine light has stayed off since day one.

Jacob ★★★★★

My 2007 GS430 was throwing a check engine light for weeks, but this converter cleared it immediately and the fit was perfect — bolted right up without any modifications.
