I talked to Ron wood last week. Thinking if buying his exhaust for the heat and weight savings. He said they have done lots of testing and the maverick does not need a new fuel controller with his system. I have looked all over the web. That appears to be true. Has anyone had experience with this? Is there a good auto tune "plug and play" controller that I should buy? Also I hear that exhaust makes little to no h.p.? If it removes all the heat, then after the machine is hot it would naturally keep making the same consistent power over a stock machine that would be choking from all the heat. Regardless of a "dyno number"! Heat kills motors. Let me know if you have any good insight on this, thanks!
