Magnaflow Catalytic Converters - 49 State Legal Reviews


Great

Reviewed By Paul V (Green Bay, WI) Reviewed for a 2003 GMC Sierra —6/4/2015 6:02 AM

I bought the: Magnaflow Catalytic Converters - 49 State Legal Universal Fit Part #: 99209HM Had them installed for $150. They replaced the original ones on the truck with a stock exhaust (6.0 GMC). They seem to make the exhaust sound a little deeper in tone, which I like.

AutoAnything cam through again....

Reviewed By Robert O (Apple Valley, CA) Reviewed for a 2014 GMC Sierra —12/14/2013 1:38 AM

Not only did AutoAnything deliver in less than 24 hours, but the price with the Black Friday discount and free delivery blew everyone else out of the water... Had the cat installed on a Monday and my truck passed it's Smog test with flying colors.. Not bad for a 20 year old Yukon 2 door, 4x4... Thank you AutoAnything...

Does the job

Reviewed By Thomas L (BEAVERTON, OR) Reviewed for a 2002 Jeep Grand Cherokee —5/31/2016 6:13 PM

Not as sturdy (or heavy) as the OEM, and much thinner pipe walls. But it does the job nicely. Of course, I can't say yet if it will last as well, but then again I don't need it to. The OEM lasted 14 years and 226K miles with occasional off-road abuse. So if this one lasts 6 years and 100K miles it's probably enough to live out the car, and I'll be satisfied with that.
