has anyone used an fmf megabomb or powerbomb exhaust.any feed back heard they make good power.

i had the powerbomb on the old 400ex and i loved it with a hmf pipe. made a lot more power than stock headpipe and sounded great. took the loud obnoxious hmf down to a nice cool rumble. i noticed a great deal in bottom end power and a little on top but mids stayed close to the same.

man i seen a dyno graph where it lost power over the stock pipe but believe half wut u see and none wut u hear that said they make good durable pipes tho im not trying to hate

thanks and your right because dyno numbers can be padded.
