  • Improves horsepower, torque, and throttle response
  • Increases exhaust flow and power over stock
  • Loud and aggressive exhaust tone

This HKS Hi-Power Exhaust comes with a 65mm large diameter pipe and full straight structure reduce the exhaust pressure to 50% of the stock. This significant exhaust pressure reduction enables the turbine to run smoothly from low RPM range, which results in the engine output increase in an entire speed range.

Sounds excellent as you'd expect from HKS. Fitment and finish is top shelf. It's everything I ever expected from the legendary company.

Nice sound

Installed this on my 2018 civic si. Sounds really nice, not too loud not too quiet, just perfect. Noticed a better engine response but for the most part got it for the sound. Easy to install.
