Flowmaster Super 10 Series Mufflers Reviews


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 .

The exhaust is awesome! Truck sounds really good. I have a cold air intake as well. Definitely notciable both inside and outside the vehicle. Highly recommended.

Flowmaster 70 Series Big Block II Mufflers Reviews


Flowmaster 70 series big block

Reviewed By Chad H (Lake Charles, LA) Reviewed for a 2013 GMC Sierra —3/29/2017 4:55 AM

Overall, I am happy with the muffler. As my daily driver and primary family vehicle used for traveling, I didn't want anything too loud. This muffler is a little louder than what I expected, comparing to a 50 series installed on same truck. I removed the 50 series last year and had to go back with the factory muffler due to a drone when pulling my trailer or boat. Using Flowmaster's sound chart, I thought the 70 series would be only choice as it looked to be the quietest muffler Flowmaster makes
