Magnaflow Direct-Fit Catalytic Converters - Federal 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.

Flowmaster Direct-Fit Catalytic Converters (49-State Legal) Reviews

Awesome replacement

Reviewed By Marco O (Smithsburg, MD) Reviewed for a 2006 Ford F-150 —2/21/2018 11:15 AM

Great price for high flow cats! I love around with some leaking headers for a long time - a little too long. Damaged the stick cats and the dealer wanted $3000.00 for them. I remember a buddy had to replace his a few months ago on his Toyota and he said they $3000.00. I laughed and said no way, but it's true. Anyway Autoanything saved me alot of money on these and shipped them out fast, minimizing my down time. Truck is back together and running great. Thanks alot.
