I'm starting to tinker with my truck improving the intake and exhaust flow while monitoring the egt. I figured a cheap way to help exhaust flow would be to cut out the muffler and replace with a piece of pipe.Any of you guys seen any improvement with this easy modification?

helping the exhaust will help the motor:tu:
