[QUOTE="jowoo919, post: 1424228, member: 107888"] I applaud you for taking on a project like a custom engineered expansion chamber! I thought about replacing the one on my bike because it had a medium sized dent and I thought that was hurting it alot when I read how an expansion chamber works...figured the gases were not bouncing around right in the chamber. Ended up seeing an article somewhere about doing testing on how dents effect a chamber on a 125cc bike. They tried all different sizes of dents on different parts of the chamber and did not see any adverse effect on performance and in some cases even saw a slight increase in HP on the dyno! Point is I don't think the pipe is that big a deal anymore after reading that article, sure it makes a little difference in how the power band hits but doesn't seem like it'd be worth it to make a custom pipe if something like a dent could make it run better lol. Maybe don't make it a giant project to try and craft some custom pipe that won't make too big a difference. But hey, if you do it then right on! My 2 cents :) [/QUOTE]
