Did the exhaust add any noticeable power improvements?

I hear those type of head design isn't efficient in cooling, causing the motor to run extra hot?! I don't know if it's true or not but just throwing it out there. BTW, how much improvement do you think it made in terms of more MPH?

No idea on mph gains maybe a couple mph? I had jetting issues with the bike at first. No over heating issues yet but I live in Maine and it's still cold about 40-50f atm. 60f on a lucky day. The head mostly made the bike more snappy the engine has always been fast but now once you crack the throttle it gets up there quickly. Needed to use that head design because of how the expansion chamber mounts up and goes directly over the head.
