Think this will be a good upgrade in the future? Anyone ever use it?

I know that is bad *** but due to $$n reasons I will prolly just go with a monster coil.

400ex's are not high revving machines. By the time they hit the stock rev limiter they are basically done making power. I don't think that is worth the money at all. But it sure does look cool, for what it's worth.

Those have been out for prolly 8-10 years now I know very few if any people with them. That would tell me there not worth it. Everyone was doing everything to squeeze every tenth of a hp out of the 400's and yet hardly anybody used these these.
