FMF exhaust products

I have the FMF power bomb on my 03 yz450f. Im just curious as to what the difference, performance wise, between the FMF power bomb and the FMF mega bomb

The bomb is supposed to give it more low end. However it loses top end at the same time.

I have a 09 yz450f with a mega bomb and power core 4.1 I love it on mine spreads the power and it Really smoothes the power of you do loose on the top end it isn't enough to matter I never been riding where I had a chance to really open it up I do single track so yea

Is their a difference between a power and a mega bomb aren't they the same?

Yea as far as I know they are

Is their a difference between a power and a mega bomb aren't they the same?

No. One has a big bulge and the other is way smaller.

I tried a mega bomb on my built 450 and it sucked on top end. So I got rid of it.

FMF has spoken :).

The Megabomb technology is revolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. The Powerbomb is more focused in the mid to upper RPM range use for more high speed to end style riding.
