Magnaflow Catalytic Converters - 49 State Legal Reviews


Better than stock

Reviewed By Jason H (Carrollton, TX) Reviewed for a 1988 Mercury Grand Marquis —6/9/2009 8:42 PM

But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

Great Product for a great price!!!!

Reviewed By Daniel B (LONG BEACH, CA) Reviewed for a 1999 Pontiac Grand Prix —5/11/2016 1:21 AM

Item was shipped fast. After opening the box, the downpipe looked beautiful. Nice welds all around and was even supplied w/gaskets (however I would have liked the gasket that goes from the exhaust manifold to the downpipe to have "ears." This would have helped w/installation). Nevertheless, installation was quick and simple. 4 bolts along w/replacing the O2 sensor. What I love most about this product is that it eliminated the "U Bend" that the stock downpipe had. Do not regret spending $500.

Great Replacement

My factory cat converters were burned out so I found these replacements. Way cheaper than overpriced dealer parts. Truck is now ready for smog test!
