The FMF Factory 4.1 Titanium Full Systems are the holy grail of aftermarket exhaust upgrades. Combining a Titanium Factory 4.1 Muffler with an FMF Titanium Megabomb Header pipe, you'll want to make sure you're holding on to your pants when you take this thing out riding for the first time. The Factory 4.1 Muffler will work wonders when it comes to improving the overall speed and power of your four-stroke machine - these are the very same pipes that you find on professional race team bikes all around the world - straight out of the box. And with the Megabomb header providing you with everything you need when it comes to bottom to mid-range torque and responsiveness, you'll find yourself dealing with a whole new beast next time you head out riding.
