HKS 33005-AT007 Manifold GT Spec with Catalyser Toyota 86/ Subaru BRZ (MT only!)

■FEATURES

• We choose 4-2-1 layout for best performance. It's a special smaller size design but still cleared the Japan Exhaust gas regulation because we used more purification material in the catalyzer.
• We have renewed the design of the layout and catalyzer for less pressure. 4-2-1 exhaust manifold efficiency is greater with the new design and normal to high RPM range provides more power.
• Acceleration response is much improved in the normal RPM range. And stock's normal power for the high RPM range has improved to more power output. You can enjoy driving fast.
• It's made of strong material SUS304 which is good for circuit use.
