Benjamin X. ★★★★★

Swapped out the old clogged converter on my SC430 and the MagnaFlow bolted right up with zero hassle. The mandrel-bent tubing is a nice touch for a cleaner exhaust note, and no check engine light issues after a week of driving.

Brian ★★★★★

After hundreds of miles on my 2007 GS430, the check engine light has stayed perfectly off, and the mandrel-bent tubing gave me back a touch of low-end torque I didn't realize was missing.

Elizabeth F. ★★★★★

Bolted right up to the factory mounts in about an hour, and the mandrel-bent tubing keeps the exhaust note deep without any drone. Check engine light has stayed off for two weeks of daily driving, which is exactly what I needed for California smog.
