Hard Krome 2.5" pipes with Accessory Slashcut Endcap.
A slightly richer condition may occur on motorcycles over 1100cc.


2 Hard Kore Quiet Baffles, 
1 Allen Key, 2 Allen Screws,
1/8” Drill Bit, 1/4” Drill Bit.

Use Loctite on all screws.

1. Remove exhaust end cap by unscrewing exhaust allen screw with allen key (supplied).
2. Locate countersunk hole on end cap adjacent to threaded hole (choose one).  Take 1/8” drill bit (supplied) and drill a starter hole.  Take 1/4” drill bit (supplied) and drill hole. (A new hole is required as original threaded hole will bind with our baffle thread.)
3. Important – put a bead of High Temperature Silicone Adhesive Gasket Maker or similar in the end cap to seat the baffle into the end cap.  Place baffle in endcap.
4.  Insert end cap and baffle assembly into the exhaust.  Secure with button allen screw.  

NOTE :  As with all motor modifications, some rejetting may be required.  The baffles may create a slightly rich condition in some circumstances.
