I used the megabomb with an fmf speed muffler on my yz250f. It really woke it up everywhere. I trail ride, so I wanted more grunt. I got it and an awesome mid to top. This thing will rev to the moon. This is money well spent.Read All Reviews

It is very easy to install. For my KFX450R, take the end cap off and there is a recessed area that it fits right into. The flange was slightly thinner than the recessed area, so it rattled a little, but not bad. The db's are difinitely reduced by a very noticeable amount. Performance was not reduced at lower rpms, but the reduced diameter of the quiet core pipe definitley robs some mid and upper rpm power. Usually the atv would easily wheelie while riding in the woods/trails in 3rd adn 4th gears with just little rises in the trail. This was not happening with the quiet core installed. Still if you are going somewhere that requires reduced db's then this will get your atv qualified.Read All Reviews
