Okay what if I told you that I have a product that lasts five times longer than standard packing to maintain peak power and performance. Improves power and low-end throttle response with consistent packing density. Allows silencer to flow freely to maintain top-end over rev. Economical-requires re-packing much less often reducing maintenance time packing cost. User friendly- packs fast and less irritation to the skin unlike normal fiberglass packing. Love what you have just read well then you want Race Tools Max Pack Cartridges.
