Functionality meets performance with the new HKS Legamax Premium Exhaust System for the 2017–2021 Honda Civic Type R. This system was developed to be comfortable enough for daily use, but add desired performance to match the character of the Civic Type R. The large diameter pipe and full straight structure reduce the exhaust pressure to 50% of the stock.
The serrated/helix design of the aFe Power Silver Bullet Throttle Body Spacer creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber, resulting in increased performance and improved throttle response. The serrated/helix combination design also reduces intake whistle that occurs with helix-only designs.
Unleash performance gains of up to +10 horsepower and +11 lb-ft of torque with aFe Power's Takeda 3.0-inch to 2.5-inch mandrel-bent, 304 stainless steel cat-back exhaust system for the 2017–2019 Honda Civic Si Coupe. This cat-back exhaust system consists of dual free-flowing stainless steel mufflers which produce a deep, aggressive tone. aFe Power completes this exhaust system with dual tips which are 100-percent hand TIG welded for strength and durability.
