HKS Super Turbo Muffler - Urban Matte Edition: The Ultimate Sophistication for Your GR Supra

Introducing the HKS Super Turbo Muffler in the sleek and refined Urban Matte Edition, designed exclusively for the B58B30C-equipped Toyota GR Supra (Model DB42, 2019/05 - 2020/09). This latest version takes the aggressive sound of the HKS exhaust and wraps it in a sophisticated matte finish, transforming your Supra's rear end with an elegant yet rugged aesthetic.

Design & Craftsmanship: The “Urban Matte” tailpipes feature a unique matte finish, retaining the cool and rugged texture of the metal while offering a soft and elegant shine. The attention to detail extends even inside the tailpipes with a finely crafted inner slit, demonstrating HKS’ commitment to unparalleled craftsmanship. Handcrafted by master craftsmen who specialize in precision welding, each exhaust is a testament to HKS' dedication to performance and quality. The laser-engraved HKS logo adds a subtle yet refined touch, completing the exhaust's exclusive look.

Performance Features:
