Magnaflow Performance Mufflers Reviews


Magnaflow muffler

Reviewed By Dawn D (COLLEGE POINT, NY) Reviewed for a 2013 GMC Sierra —7/21/2015 9:26 AM

So far so good. Purchased as a surprise for my husband delivery was quick, installation was easy done at a local muffler shop. He was quite surprised when I picked him up and had him drive she has just enough sound to take notice but not be overwhelmed.

2015 GMC Sierra Denali 6.2L Magnaflow Cat Back Exhaust

Reviewed By Rick T (East Peoria, IL) Reviewed for a 2015 GMC Sierra —7/4/2015 10:56 PM

Overall, very pleased with the Magnaflow exhaust. Two of the four hangers were off a bit and had to be adjusted, but I am a perfectionist. They probably would have been fine but now they are perfectly aligned. Exhaust has a very nice throaty sound when accelerating and quiet when cruising. Has a pretty good rumble when starting cold. Not too crazy about a five inch exhaust tip. Kind of makes it look like a diesel truck exhaust. The more I drive the truck with this exhaust, the better I like it.

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.
