The HKS Super Turbo Twin Tail Titanium Tip cat-back exhaust for the 2015-2021 Subaru WRX and WRX STI is a limited 45th Anniversary Edition — only 45 units were made worldwide to celebrate HKS's 45th anniversary. It uses the popular Super Turbo design built from 100% titanium alloy for an extremely light system. The Super Turbo muffler combines a low back-pressure design for improved power and torque with low sound levels at low RPM for comfortable street driving, cutting exhaust weight by about 50% compared to OEM while keeping the dual-exit quad-tip layout.
