The TRD cat-back exhaust delivers the increased power you want, adding a distinctive edge to your driving experience. Made from stainless steel for superior corrosion resistance and featuring a TRD-logo-etched tip, the unique cat-back design features a side exit to maximize departure angle, allowing for a less restrictive exhaust path--providing an impressive combination of increased horsepower and a deep, throaty growl that meets the legal 95-decibel noise limit.
