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.

Volvo catalyst

Reviewed By Kevin M (Milton, MA) Reviewed for a 2002 Volvo S80 —9/7/2015 7:12 AM

Catalyst arrived very quickly however packaging was beaten to pieces. Package included all gaskets and heat shield securing bolts (unexpected !). Overall very pleased with the speed of delivery and quality of product but would like sturdier packaging.

Reviewed By Thomas V (PLYMOUTH, MI) Reviewed for a 1999 Chevy Suburban —8/29/2015 3:59 AM

The Flowmaster Catalytic Converters were a proper fit, there is some resonance that I am working to get rid of, but overall I am happy with my purchase, it arrived quickly and was what was ordered.
