The Sparks Racing X4 Stainless Steel Exhaust system is the ideal exhaust system for any application because of the power gains it produces through the entire power curve. Our exhausts are complete systems, not slip-ons, because we’ve found much more performance with designing a complete system rather than working with the limitations of the stock head pipe. Some aftermarket exhaust systems are able to be used as a slip-on or complete system, but the problem is they’re still limited to stock diameters where the head pipe and rear section come together. We have spent countless hours testing on the dyno, on the track with Pro-level riders, and at the drag races to insure the most performance possible out of our exhaust systems. The X4 Race Core features an ideal outlet diameter which offers the best all-around performance and can be configured with a spark arrestor and quiet inserts. The Race Core system is about 100db using SAE testing guidelines.
