Magnaflow Exhaust Systems Reviews


Hummer H3

Reviewed By Gregory B (Leavenworth, KS) Reviewed for a 2007 Hummer H3 —9/26/2008 9:04 AM

Purchased the magnaflow exhaust system inconjunction with the True Flow air intake system for a Hummer H3. I installed the air intake system myself. It was simple, just as the instructions described. I had the magnaflow exhaust system installed by a professional shop. It looks and sounds great. Not too loud. Just a little more depth to distinguish it from the stock system. I have noted a slight increase in fuel mileage since installing both systems. This was a primary motivation for purchasing both systems. Hopefully, fuel mileage numbers will improve after more driving and fillups. Overall, I am quite please with quality, look and sound of both systems.

Magnaflow Performance Mufflers Reviews


Not Quite What I Expected but Still Like It.

Reviewed By Dan S (Coldwater, OH) Reviewed for a 2009 Dodge Ram —8/12/2016 1:52 PM

Had the #12588 installed with the Y-pipe upgrade on my 2009 Dodge Ram. This is my first Magnaflow muffler, and after watching numerous youtube videos I went with the 22" in fear of the drone. I was expecting to hear more of a difference when accelerating over stock, but I'm still early in the break in process. I've noticed a slight drone around 1500 rpms, it's not bad and could go away over time.
