HKS 31019-AH108 Exhaust System HI-POWER SPEC-L II for HONDA Civic (FK7) 2017-2021

Weight reduction, low exhaust pressure, improved drivability and exhaust efficiency.

• As light as Titanium
  HKS has achieved a weight reduction comparable to the titanium exhaust system by utilizing ultra lightweight components for each part's material for pipes and silencers. The weight of the exhaust compared to factory one is reduced from about 30% up to 60%, which leads to improved driving performance.
• Improved exhaust efficiency with a straight through structure
  A straight through structure greatly improves exhaust efficiency. HKS also design exhaust for a sporty and comfortable sound based on each vehicle individual specifications.
• Titanium tail tip cover
  New series feature a titanium tail tip cover instead of carbon. Burnt titanium tail tips add to racing atmosphere. HKS now offer an optional tail tip cover*. There are three types of optional tail tip cover available. A standard titanium, a familiar carbon cover, and a new cool looking Neuse tail tip cover made with blue stainless steel.

*The replacement tail tip cover is an optional part for Hi-Power SPEC-L II.

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.
