After installing this, my truck's exhaust note got a bit deeper and the check engine light has stayed off for three weeks now. The mandrel-bent tubing looks like it'll hold up well against the rust we get here in the Midwest.

Bolted right up to the factory hangers and the check engine light stayed off through the last 300 miles, which is exactly what I needed. The corrosion-resistant shell looks solid, and the direct-fit design meant no cutting or welding on my F-150.

That mandrel-bent tubing made for a much smoother exhaust flow — I noticed a slight power bump and the truck sounds cleaner now. Passed emissions without a single issue, and the check engine light stayed off right away.
