Customer Reviews (4.4 / 5 · 5 reviews)

Victoria ★★★★★

No check engine light since I bolted this in, and the mandrel-bent tubing made for a clean fit on my Lightning's exhaust. Took about an hour to swap out the old one, and the truck feels like it's breathing better now.

Victoria ★★★★★

The install was straightforward and the gaskets provided made for a perfect seal. Since bolting it on, the truck runs smooth and the check engine light has stayed off. Feeling good that it's EPA compliant for my old Lightning.

Miles ★★★★★

Bolt-on fit was flawless on my 2004 Lightning, and the mandrel-bent tubing clears everything with zero modification needed. Check engine light stayed off after the install, which is exactly what I was hoping for with an EPA-compliant unit.
