Holeshot 4-1 Header Upgrade Kit

Kawasaki ZRX-1100/1200

NOTE: This product is not legal, for sale or use on California vehicles!

Dale has designed a slick ZRX Holeshot 4-1 header upgrade kit. This allows any ZRX-1100 or 1200 owner to install the Holeshot Header System to most current slip-on available. The Header upgrade includes the Holeshot hand made front header section, a new mid pipe with matching flange for the 1100 or 1200 bolt pattern, stainless clamps and hardware. The Holeshot header makes big power and torque gains, has total oil and filter access, more cornering clearance and is much lighter than the original factory header. One of Dale's matching jet kits are also recommended when running our system.

Note! Your current brand X slip-on must have a sliding outer muffler clamp to install our Holeshot Header upgrade system. A new style muffler clamp is included in the kit for those who own a ZRX-1100 Holeshot slip-on and second generation ZRX-1200 Holeshot slip-on.

The Holeshot header coating comes with a 1 year anti rust warranty to the original purchaser.

Note: The ZRX Front Fender Extender must be purchased for us to honor our header coating warranty. Click here to see Front Fender Extender
