"went together perfect. Must have all the original rubber hangars or you will have to buy them to be able to hang this system. All parts were a perfect fit. I like the heavy duty flange were it mounts to the cat. had to go buy a new donut gasket.wasn t one in the kit. it is truly a direct bolt on system. fits great.It may be a little quitter than I thought it would be but very happy with this product" posted by: magic legs on May 8, 2014

"Easy to install, good sound and look. If I stop stomping on the gas pedal to hear the exhaust it may even help my gas mileage a bit. The hardest part was getting the stock exhaust out from under the truck." posted by: Chris on November 21, 2008

"I just bought this for my 05 Ranger Fx4 Level ll auto, with a 4'' suspension and 33'' tires and I ran 4 tanks and now I'm getting an average of 17 mpg from normal 12-13 mpg. The H.P. gains are great you can feel the power when you step on it and you get great sound too!!!! When towing there is a great improvement as well." posted by: kcfordman01 on April 21, 2008
