Customer Reviews (4.6 / 5 · 5 reviews)

Jason E. ★★★★★

The mandrel-bent tubing is a nice upgrade from the stock pipe, and it bolted right up without any alignment issues. My check engine light stayed off after the first drive, which is exactly what I needed for California compliance.

Michael X. ★★★★★

Installed it last weekend on my 3.6L and the fit was spot-on for the direct-fit design, no exhaust shop needed. The mandrel-bent tubing keeps the flow smooth and the check engine light has stayed off through about 200 miles of mixed driving.

Stella U. ★★★★★

My check engine light was driving me nuts, and this converter finally shut it off for good. The mandrel-bent tubing made it a breeze to line up during installation.
