Magnaflow Performance Mufflers Reviews

Very good product

Reviewed By dalton w (COAL TOWNSHIP, PA) Reviewed for a 2013 GMC Sierra —11/4/2015 5:56 AM

I installed the 14" magnaflow performance muffler on my sierra. It sounds excellent, not to loud and not to quiet. Just has that perfect tone that a truck should sound like.

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...
