Graves Motorsports Kawasaki EX400 Cat-Back Slip-On exhaust. Our exhausts are hand-made in the USA for direct fitment to the 2018 Ninja EX400. This slip-on exhaust is new from the ground up with record breaking race developed features. Graves’ engineering develops precision products that are designed to outlook, outperform and outlast the competition. This product retains the OEM cat system and is intended for closed course competition use only.
New Silencer Design Featuring: Carbon Sleeve with Carbon Fiber End Cap and stainless steel exhaust tubing. Strapless silencer design mounts without the use of a strap band around the silencer, by using a top mounted bracket that’s structurally integrated into the silencer. This design not only streamlines looks of your bike, it also saves weight. This system comes standard with a quiet insert that reduces sound and creates back pressure to improve performance on this model.
