Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin ★★★★★

The mandrel-bent tubing really opened up the exhaust flow on my truck, and the CARB compliance gave me peace of mind. No more check engine light, and it fit like the original part.

Sophia S. ★★★★★

Bolted right up to my 2004 F-150 without any modification needed, and the mandrel-bent tubing makes the exhaust flow feel noticeably smoother than the old clogged unit. The check engine light has stayed off for the past 500 miles, which is a huge relief.

Harper ★★★★★

Cleared the P0401 code on my 2004 F-150 after a few hundred miles of mixed driving, and the CEL has stayed off for three weeks now. The direct-fit design lined up with the factory hangers without any persuasion, which saved me a trip to the exhaust shop. Corrosion resistance was a big selling point
