this pipe mounts behind the motor and the exit of the exhaust is also behind the motor so there is no heat or exhaust contamination under the body and there is no hacking of the body only a small hole needs to be made in the plastic side guard for the exhaust exit, it is completely out of the way if you need to work on anything other than the motor. This is the Losi MTXL pipe in raw finish , it will produce more power than a plated pipe and can be made and shipped the same day and is cheaper than a plated pipe it is a no leak two piece design that mounts solely to the motor to insure the release of vibration without putting stress on the pipe due to chassis flex, it can be ordered in silenced or non silenced and will double your power in all three power bands
