Default Re: "TUNABLE EXHAUST"- A valid concept?

Also, notice even dragsters run pipes off the head. The idea is to have the length correct (in other words tuned) so that the exhaust from the previous cycle is exiting the pipe causing a low pressure area inside the pipe to help pull the gasses out of the cylinder on the next exhaust stroke.
