is it possible to do that?

what performance gains would I see?

as long as it bolts up to the cylinder and right past the megabomb part, can do custom till i get to the muffler

I have the PowerBomb in a 2000 YZ. Bolted right on to the existing (stock) muffler, no problem.

I bet the MegBomb is the same.

I noticed some low-to-mid throttle response increase, maybe some low-to-mid increase in power too. Helped a lot on the tight trails.
