I know this video is a year old but 500 bucks for the stage 2 kit sounds insane considering the exhaust alone on TRS's website is currently 750 bucks by itself and they show out of stock.

How much faster was stage 2 compared to stage 1?

Hey bro! How can I get in contact with you? I have a few questions would love to work together dude!!!

Did you rejet the carb? More air in = more air out which means more fuel required (more than the power stack can provide)

Dirt getting in the engine will smoke those little motors..
