I self installed a Flowmaster Catback exhaust. VERY doable if you know how to work a wrench. I love it. I cannot imagine there will be ANY reliability issues. Some might say the decreased back pressure can be hard on the exhaust valves / engine. These are turbocharged motors, so the turbine provides plenty of back pressure when the motor is pressed hard. See my thread here for more info: https://www.ranger5g.com/forum/thre...-back-exhaust-system-install-with-mods.12307/What are the pros and cons of an aftermarket exhaust?
Is it healthier for the life of the Ranger to leave the stock or better to put on a aftermarket exhaust?
