Magnaflow Exhaust Systems Reviews


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.

00 GMC K2500 7.4

Reviewed By Joshua V (Elkhorn, NE) Reviewed for a 2000 GMC C/K 2500 —6/23/2015 9:40 PM

A nice system, I was in need of a new muffler and was wanting a stainless muffler, there is a noticeable amount of power increase with this, as it increased it from 2.75 to 3 inches and a lot better flow through the muffler, I was worried that it was going to be to loud but its not, I don't like loud gas engines, there is a little rumble out of it now when accelerating hard but cruising it is still nice and quiet,came with nice directions and everything needed for the installation.

Flowmaster Exhaust Systems Reviews


Great sounding exhaust

Reviewed By Jack D (Somerville, TN) Reviewed for a 2001 GMC Sierra —6/16/2015 5:59 AM

Flowmaster has always made great sounding exhaust. I had to remove an aftermarket hitch because the side brackets were too low and my son wanted the exhaust out the side. I found a factory hitch that fit with no problems. Other than that, which wasn't Flowmaster's fault, the exhaust install was very straight forward. We are very happy with the look and sound.
