HKS SILENT Hi-POWER NA GF-AP1 F20C

This HKS SILENT Hi-POWER NA cat-back exhaust system is specifically designed for the GF-AP1 F20C engine application. It replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and deliver a refined sound profile without excessive noise. The system is constructed from SUS304 stainless steel, known for its durability and resistance to corrosion, ensuring it holds up well under various driving conditions.

The SILENT Hi-POWER design focuses on balancing performance gains with a comfortable sound level. It features a larger diameter piping and a specially designed muffler to reduce backpressure and enhance exhaust scavenging, which can lead to a more responsive engine. The internal baffling within the muffler is engineered to quiet down the exhaust note, making it suitable for daily driving or situations where a loud exhaust is undesirable. Installation typically involves unbolting the stock exhaust and bolting on the new HKS system, though specific hardware and alignment may require careful attention.

This cat-back system is a well-built option for owners looking to upgrade their exhaust for a better sound and potentially improved performance. It's a popular choice for those who want a noticeable improvement over the stock exhaust without the drone or loudness often associated with less refined aftermarket systems. Ensure you check all included hardware against the parts list upon arrival to confirm a smooth installation process.
