Push Industries introduces its own Factory Pipe replacement coupler, complete with hose clamps. This is not your standard thin coupler designed for a car's air intake system, but rather a purpose-built part meticulously crafted for durability and performance in a two-stroke exhaust system. Not all silicone couplers are created equal. Standard silicone couplers are typically unsuitable for oil or fuel applications. Push Industries employs a two-part construction process (black & orange) that incorporates a fluorolined layer, ensuring longevity when used with 2-stroke exhaust systems exposed to oily engine fog from the exhaust. A significant portion of the lower-priced, single-color silicone tubing available on the market today is tailored for air intake systems that will never encounter fuel or oil. Compatible with "A" and "B" Headpipes, including those from Kawasaki, Yamaha, and Polaris Wet pipes, this coupler (DIMENSION 4"X 2 1/8") sets itself apart from the competition. Unlike thinner alternatives on the market, this Push Industries coupler is specially engineered from high-heat silicone hose, capable of withstanding the rigors of modern stand-up riding, including vibration and abuse. It's tailored to expand and endure, meeting the demands of today's riders, while guaranteeing a reliable fit and optimal performance with a range of pipes.
