The HKS Super Manifold with Catalyzer GT-Spec is a highly efficient metal catalyst and 4-2-1 isometric layout to achieve excellent exhaust efficiency.
Features
- This product uses a low-density metal catalyst, as opposed to the genuine fine ceramic catalyst. Exhaust resistance is greatly reduced.
- While using a low-density cell, the blending ratio of precious metals is optimized to comply with the 2018 exhaust gas regulations. We have obtained certification from a third-party organization.
- Adopts a 4-2-1 isometric layout. The complete isometric layout is realized by repeatedly examining the layout of the four parts.
- The head side flange has been redesigned to improve the stepped portion where the pipe is inserted, and a newly designed flange has been adopted.

HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
