HKS Hi-Power SPEC-L Auspuffanlage Edelstahl 2.5'' (Civic 2017+ Type R FK8)

HKS SPEC-L II Exhaust system.To maintain the exhaust efficiency, enlargement of the exhaust pipe is usually required; the sound level tends to be increase and low-tone. The exhaust system with a cannon ball-shaped shell usually has lower silencer capacity than an oval-shaped shell; therefore, to reduce the sound level, the pipe diameter is narrowed. However, a narrow pipe diameter also reduces the exhaust efficiency and increase the exhaust pressure.

HKS utilized original unique technology to maintain the exhaust capacity and sound level to meet the JASMA standard which is more severe than the regular safety standard. Inner structure of the silencer was redesigned so the unwanted low exhausts resonance was eliminated, and the sound quality was improved.

Concept and Features

- Remain the basic concept of "Light weight", "Low pressure", "Sporty sound" and evolve with new tips for stylish appearance.
- Super light weight is achieved by using plenty of extremely thin SUS304 materials in 0.8mm pipe and 0.5mm silencer outer.
- Straight pipe layout for low exhaust pressure.
- Optimized silencer allows to enhance low tone and remove all unpleasant noise at the same time.
