[QUOTE="Matt90GT, post: 1366448, member: 30871"] i believe the X is the same bike as when they came out. Here is the deal, do you want power at the expense of sound or just quiet power? Reason being is the X pipes are restrictive. You can replace them with an aftermarket unit like a PC or MRD and still be down about 96 db, but they are louder than stock. But a high compression piston and cam are easy ways to up the power without modifying the exhaust. Always go big bore to. [/QUOTE]
