Designed to offer good power gains while keeping exhaust volume in check, the HKS Legamax line of exhausts is perfect for a daily driven Subaru WRX STI. Each Legamax system uses properly sized exhaust piping, and mufflers specified to minimize back pressure to increase horse power, yet still deliver solid low end torque. These exhausts are meant for street driven performance and deliver uncompromised power gains and sound control. Some kits are available in center sections only, which can be used with either the HKS Legamax muffler assembly, or the stock muffler to keep volume to a minimum while still offering power gains from the increased exhaust flow. Available in piping diameters from 50mm to 85mm depending on application, and tip sizes up to 120mm.
