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.
