Zoe S. ★★★★★

The mandrel-bent tubing made installation straightforward on my 2015 Expedition, and the check engine light has stayed off for two weeks now. Fits exactly like the factory piece but feels more solidly built.

Carter P. ★★★★★

I was relieved this direct-fit converter lined up perfectly with the factory hangers on my 2016 Expedition, no modifications needed. The check engine light stayed off after installation, and the mandrel-bent tubing feels solid. Only gripe is the nuts could be a little thicker, but it's been working

Ava U. ★★★★★

Bolted this in over a weekend and the fit was spot-on for the 3.5L, no cutting or fussing with the hangers. The mandrel-bent tubing keeps the exhaust note smooth, and I’m two weeks in with zero codes.
