Torque Solution offers upgraded polyurethane mounts for your WRX or STI to reduce exhaust movement and vibrations. OEM rubber mounts sag over time and let your exhaust sway about which can possibly cause cracking and gasket leaks. Torque Solution uses the highest quality 75A durometer polyurethane to ensure your exhaust stays put. Made in the USA and track torture tested, you can be sure these mounts will last forever! These complete kits contain enough mounts to do your entire exhaust. Two variants are offered, standard and long. The long version allows for more clearance from the undercarriage.
