Flowmaster 817539 Force II Cat-back Exhaust System

The Cat-Back system was a pain to install. There are too many connections to install. Some of the clamps were difficult to get tight enough to stop exhaust leaks. I even twisted one of the clamp bolts in two trying to get one of the connections tight enough to hold the two pipes from twisting and wiggling. The exhaust tips were impossible to get aligned and look the same on both sides. I also had to buy two hangers to get the tail pipes stable before exiting at the rear bumper. They look ok but are not equal on both sides, They sound ok but they are installed on a Ford v6 3.5L ecoboost truck. I guess nothing will really sound good on a V6. I can't really feel and increase in performance but they are louder than stock pipes. I might add..I installed a K&N intake system and thought the exhaust system and intake system would really make my truck come alive but I really can't see any improvement in performance.
