Rated 5 out of 5 by Awesome Awesome product! January 29, 2015
Rated 5 out of 5 by Great exhaust! One of the best upgrades to make a car / truck more aggressive. Lots of great throttle blips and burbling on up and down shifts! March 8, 2014
Rated 5 out of 5 by Flow Master 44 Series This product did everything I expected. Gave me the sound I was looking for and added prefomance. I was initially concerned about interior sound. Though it is louder then the stock muffler, my wife is still able to talk over it. In fact she didn't even really notice the difference. My 21 year old daughter did however, and immediately asked if she could drive my truck. Installation was easy enough, however, the stock muffler was almost double the size so , 3 inch intake and a 12 in out pipe was needed to match up to the exsisting pipe. cost about 10.00 more bucks total at Pep boys. I would recommend this product, and I would recommend getting it at Pep boys. After looking all over the web it was the best price in town. June 10, 2013
