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.

Great Exhaust.

Reviewed By Chris B (LANCASTER, OH) Reviewed for a 2007 Nissan Frontier —3/25/2015 1:34 PM

Exhaust is great. Quality and appearance is great, but you pay for it. Sounds good, but I don't get any noticeable power increase. Magnaflow should have made this exhaust go all the way up to the catalytic converters. I think the factory y-pipe still constricts the exhaust too much.

Magnaflow Muffler

Reviewed By Marwan Y (BOGART, GA) Reviewed for a 2011 Ford F-150 —3/18/2015 4:43 AM

Great sound for those looking to unleash the beautiful sounds of an American V8. Its not to loud which is perfect for those who enjoy hearing the person next to them while driving. tone gets better as it breaks in.
