easy to install, no mods needed. Makes the truck sound nice when i hit the gas! (may defeat the purpose of gas saving....lol)

Took it to an installer due to having to cut out old exhaust. Sounds great. Quite through the gears, nice rumble. Gets louder when the engine goes down to four cylinders. But, overall very happy with sound. I can feel the extra power when going up hills.
