RAM 1500 HEMI - just the sound I was looking for to bring out the beast in my engine. The price point was better than I expected, noticible performance and fuel boost, and easy installation as a bolt on. Can't go wrong with Flows.

Bought a flow master cat back exhaust system for my 2015 dodge ram 1500 with a hemi. It sounds great!! Not overly obnoxious, but a real nice growl.

Exhaust system was easy to install. It sounds stronger than original system.

Hardest part was taking out the factory exhaust

The Flowmaster system sounds great! Not to loud when you are driving down the road but lets you know your driving a Hemi when you step on the gas. The Flowmaster system was a direct fit, hardest part was taking out the factory system. I installed the system by myself in less than 1.5 hours.

awesome products.

The most difficult part of the installation was removing the stock exhaust. Installing the Flowmaster kit was easy enough, but no matter how much I tweaked and adjusted the tailpipes I could not get the tips centered perfectly on the bumper cutouts. Also, they stick out about 1 1/2 inches further than the stock tips. I'm going to take it to a muffler shop and have them center and shorten the outlets and weld everything. Sounds good, and even better with my new K&N intake!!

Awesome
