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


perfect sound and stainless too

Reviewed By William P (Mount Vernon, TX) Reviewed for a 1938 Buick Special —4/12/2018 4:58 PM

Used these on a street rod with 350 sbc 300 HP show car. Sounds good at idle and wakes up when you romp on it. They almost eliminated a drone problem.Just loud enough to let everyone know the car is not a wimp. Would definitely buy again.

Quality and Performance

Reviewed By Reese J (Idaho Falls, ID) Reviewed for a 1992 Honda Civic —4/3/2018 8:38 PM

The sound is deep and throaty. I gained about 2 mpg with a catback exhaust replacement. Maybe not the best value for the money, but the quality is worth it.
