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.

Mag Cat review

Reviewed By Craig G (Melbourne, FL) Reviewed for a 2001 Honda Civic —1/17/2018 1:54 PM

Amazing product! The original hp is back with better peddle response and a noticeable increase in hp/torgue from mid range to redline! The only reason for not giving all 5 stars in every category is after spending over $500 on this product magnaflow does not include all the necessary hardware. I had to buy new nuts, bolts and washers to connect downstream of the cat since the factory bolts are welded in place they obviously stay with the old removed component! Really Magnaflow???????????????????
