The HKS Super Dragger Exhaust is the ultimate exhaust for your Mk3 Toyota Supra! Constructed from high-quality SUS304 stainless steel, the HKS Dragger Exhaust features large 85 mm (3.34") tubing for ultimate flow. This exhaust system features a large stainless steel seamless muffler with a highly polished HKS logo on the 120 mm angle-cut tip. This is a cat-back exhaust system and connects to the catalytic converter or test pipe. Like all HKS exhaust systems, the Super Dragger Exhaust system includes the gaskets and hardware for installation. With the HKS downpipe and either a high flow catalytic converter or test pipe, this system is capable of considerable horsepower gains on the 7mgte! This system decreases backpressure while increasing exhaust flow and turbo response. Even though this system has a large muffler canister, it is actually fairly quiet and does not produce much drone on the highway. It really wakes up up 4000 rpm in loudness! Professional installation is recommended!
