That check engine light was driving me crazy for months, but this converter finally killed it and my truck sounds surprisingly good now. The mandrel-bent tubing made it easy to line up with the factory hangers, no wrestling required.

Bolted right in without any modification needed, and the direct-fit design made the whole job take less than an hour in my driveway. Check engine light stayed off through the first 500 miles, which is exactly what I needed for passing emissions.

The mandrel-bent tubing really opened up the exhaust flow on my 5.4L, and the check engine light stayed off after install. It fit perfectly without any modifications needed, which saved me a trip to the shop.
