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.

It's not my first time around with Magnaflow

Magnaflow consistently puts out high quality systems.I've tried the others, but, when it comes to overall appearance and quality, I am sticking with Magnaflow. I like the great look of the logo on the tips.

As a long time user Magnaflow once again was spot on in all aspects for my latest build.
