Flowmaster Cats

Reviewed By Jonathan G (KINGWOOD, TX) Reviewed for a 2005 Mercury Mountaineer —7/30/2014 8:52 PM

Replaced the OEM primary cats with the Flowmasters and got a high quality product for a very reasonable cost. Very happy with the end result.

Eastern Catalytic Direct-fit Catalytic Converters - 49-State Legal Reviews

Works well

Reviewed By Michael F (RALEIGH, NC) Reviewed for a 1997 Land Rover Discovery —11/28/2015 5:23 AM

I got this to replace my original catalytic converter on my Land Rover D1. I replaced the entire exhaust system, all the way down to the manifolds. The cats work well on my car, since my car is more mechanical than the new models. The system sounds great now, and I couldn't be happier. It's only been a couple of weeks but hopefully I won't have to replace it ever again.

Reviewed By Paul D (Rialto, CA) Reviewed for a 1992 GMC C/K 2500 —8/24/2015 8:34 PM

This unit solved my issue in passing the California Smog Test... A 1992 5.7L is as clean as any new car today! (HC= 14/7, CO=0.03/0.02; NO=299/34) WOW! I should have replaced my old Catalytic Converter & O2 Sensor units first and stop worrying about the test results.
