Richard Y. ★★★★★

This direct-fit converter slid right into place on my 2018 F-150, no welding needed. The stainless steel shell feels solid and the check engine light has stayed off through two full tanks of gas.

Hazel I. ★★★★★

The mandrel-bent tubing keeps exhaust flow smooth, and the fitment on my 3.5L was pretty much plug-and-play. Check engine light stayed off after the install, which is exactly what I was hoping for. Corrosion resistance looks solid so far, so I'm confident this will last a good while.

Joshua ★★★★★

Moved my old one out after 120k miles and this dropped in with zero check engine light drama. The mandrel-bent tubing is noticeably smoother than the factory bends, and so far it’s held up through a few salty winter washes without a hint of rust.
