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.

Ordering My Catalytic Converter was- "Easy-Peasy"...

Reviewed By Greg D (Chicago, IL) Reviewed for a 2010 GMC Terrain —3/5/2017 9:01 PM

Ordering from Auto Anything was easy, fast & just what I needed after being given out-rageous(price)estimates. locally. "Ethan" was very helpful. Put me right on the product I needed. I took the info, chewed on it, called back & placed my order. I added an Oxygen-sensor & Cabin filter to the order, and was set. The Converter & Sensor came w/in 3-days. The Air filter-5. The Converter & Sensor was put on-OFF went the engine light & I had it all done at a FRACTION of the estimates. #VERYSATISFIED
