HKS SILENT Hi-POWER SKYLINE GT-R GF-BNR34

The HKS SILENT Hi-POWER cat-back exhaust system is constructed from SUS304 grade stainless steel, a material known for its strength and resistance to corrosion. This particular system is designed for the GF-BNR34 Skyline GT-R, offering an improved exhaust note and potentially better flow compared to the factory setup. The SUS304 stainless steel construction means it's built to last, handling the rigors of daily driving and spirited use without succumbing to rust or damage.

This cat-back system replaces the factory exhaust from the catalytic converter back, including the muffler and piping. HKS has focused on creating a balance between an enhanced exhaust sound and maintaining a comfortable level of interior noise, hence the 'SILENT' designation in its name. While it will certainly sound sportier than stock, the design aims to avoid excessive drone or loudness that can become fatiguing on longer drives. The piping diameter is optimized for the RB26DETT engine to help improve exhaust gas scavenging, which can contribute to a more responsive feel.

When installing this cat-back exhaust, you'll typically find it bolts up to the existing catalytic converter flange, making it a direct replacement for the stock rear section. It's a well-built component from a reputable manufacturer known for performance parts. While this system is designed for improved performance and sound, it's always a good idea to check local emissions regulations to ensure compliance in your area, as exhaust modifications can sometimes affect emissions testing results.
