The HKS designed a Dual Muffler Exhaust System for Toyota GR Supra which is capable of supporting subsequent upgrades. The HKS Dual Muffler Exhaust System maintains the full functionality of the factory valve operation by containing the use of the OEM actuator. Additionally, the exhaust note is tuned to be distinct and satisfying. Running on the dyno test, it can top up 30+ horsepower as measured internally at HKS and other external facilities. That's truly amazing!

Great experience!

My first order with kamispeed was perfect. They had the cheapest online price, and i had the hks exhaust delivered to me in 3 days. As far as the product, fitment perfect, sound perfect, appearance even better. This exhaust removes the german sound out of the mk5.
