Flowmaster Force II for 2014 GMC Sierra 1500 5.3L

Reviewed By Daniel S (BOURBON, MO) Reviewed for a 2014 GMC Sierra —3/13/2018 8:43 PM

This is a great sounding Cat Back exhaust. I didn't want it to be real loud and this was a perfect choice. Has a nice throaty sound when started and I haven't noticed any drone. Was very easy to install, took about an hour. Was delivered very fast and in good condition. Highly recommend this system and was very helpful with this purchase!

Not too shabby

Reviewed By Zackary A (BINGHAMTON, NY) Reviewed for a 2015 GMC Sierra —4/14/2017 8:19 PM

Too quiet with just the muffler . Had to cut out the resonator. Sounds pretty throaty now probably perfect for a lot of people .
