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.

Just the sound we wanted!

Reviewed By Lindsay P (San Diego, CA) Reviewed for a 2010 Ford F-150 —11/25/2014 12:42 PM

We just put this on our 2010 Ford F150 Lariat V8 5.4L and it sounds awesome! We installed it with a K&N 57 Series Intake and a Superchips Flashpaq tuner and I have all the sound and power I want. It's quiet while cruising but loud when I step on it. Install was a little difficult because I had to cut out my old exhaust, but I did it by myself and it didn't take too long. I went with the dual exhaust, performance series, side exit. I highly recommend this and the other mods to other F150 owners!
