Note: Does not fit EX or LX
Redesigned The SPEC L II muffler has been redesigned to match the bumper shape of the 2020 Honda CIVIC Hatchback. It can be installed on 2017-2019 models as well. The existing 31019-AH107 will be discontinued. Please refer to page 2 for details.
30% weight savings HKS use thin stainless-steel material for the pipe and silencer to achieve weight reduction compared to the stock muffler. Stock: 17.5kg, SPECL II: 12.3kg
Elaborated sound quality and low back-pressure It provides a sporty bass sound during the acceleration and eliminates uncomfortable drone sound at the normal rpm range. In addition, the straight structure silencer achieves about 40% less low back-pressure compared to the stock.
HKS
High performance for stock to high performance vehicles with upgraded turbines, sound quality and the JASMA standard are implemented together. This had been impossible in a long exhaust tuning history.
To maintain the exhaust efficiency, enlargement of the exhaust pipe is usually required; the sound level tends to be increased 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.
