Customer Reviews (4.6 / 5 · 5 reviews)

John ★★★★★

Bolted right up to my '04 GTO without any modification needed, and the check engine light stayed off after installation. The stainless steel shell feels solid and should hold up well against road salt.

Richard ★★★★★

The mandrel-bent tubing on this converter made installation straightforward with no extra fabrication needed. It’s been a few hundred miles and the engine light has stayed off, just like I wanted. Feels solidly built and I’m glad I went with this direct-fit option.

Andrew U. ★★★★★

My old cat was rattling like crazy, but this one uses mandrel-bent tubing and it bolted right up with zero exhaust leaks. The check engine light has stayed off since install, which is exactly what my 5.7L GTO needed.
