The Powercore slips right on and gives the CRF a noticeable boost in chug and torque on the bottom and also more meat in the mid which made it easier to pull higher gears in turns. It felt a little flat on top compared to the boost on the bottom.

Combined with the Megabomb header, this gave the CRF some serious snap on the bottom and a hit in the mid range with enhanced throttle response everywhere. The full-system also pulled longer and harder on top as well. If you like your throttle to delivery the snapping of the power without using the clutch, this system is for you.

Here the snap is tamed, especially on the bottom making the setup a lot easier to ride for some riders and without feeling like the bike lost much power anywhere else. It also seemed to let the power last longer up top. And it was noticeably quieter to the rider and on the track which was great.

This system was very similar to the stock Honda in power and pull with our testers feeling the bike gained in the upper mid-range.

This was by far the quietest system we tried and it felt very plugged up. So much that you started hearing a lot of engine noises that you didn't know were there. The power is tamed quite a bit from stock, especially on the bottom where the bike loses almost all of its snap. The pull is smooth and it makes plenty of power if you use RPM as your friend, but it always feels down on power compared to stock, like it is a 400cc bike. If you ride where noise is an issue, this is a system to consider, and likely we'll all be riding with mufflers this quiet in the future, so we better start getting used to it.Riders could also feel the weight of this muffler's mechanical sound dampening system.
