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.

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.
