HKS 99-00 Honda Civic Si Hi-Power Exhaust

HKS is a well-known name in the performance automotive world, often associated with high-quality engine components and exhaust systems that offer a noticeable improvement in sound and performance. This Hi-Power cat-back exhaust system is specifically made for the 1999-2000 Honda Civic Si, aiming to give that model a more aggressive exhaust note and better flow than the stock setup.

Constructed from SUS304 stainless steel, this exhaust is built to last and resist corrosion, even in harsh conditions. The piping diameter is 60mm, which is larger than the factory piping, allowing exhaust gases to exit the engine more freely. This improved flow can lead to a slight increase in horsepower and torque, and it definitely changes the sound of the car to a deeper, sportier tone that many enthusiasts look for. The muffler design is also part of the Hi-Power series, known for its distinctive sound profile.

This cat-back system replaces the factory exhaust from the catalytic converter back to the tailpipe. Installation typically involves unbolting the old system and bolting in the new one, though some adjustments might be needed to ensure perfect alignment. It's a popular choice for owners looking to enhance both the sound and the performance feel of their '99-'00 Civic Si.
