Description
HKS Hi-Power Dual Exhaust
Product Overview: HKS Hi-Power Dual Exhaust is an exhaust-system component engineered to improve exhaust flow and deliver HKS-specific sound and packaging. This listing is structured around the exact HKS product/SKU so shoppers can match the component to the intended vehicle or build without relying on a generic product-family description.
Vehicle Application: 2003-2008 Nissan 350Z (Z33)
Driver Benefit: A freer-flowing exhaust can reduce restriction downstream of the engine while giving the driver a more purposeful exhaust note and a performance-oriented appearance.
Recommended Use: Best suited to street and track-oriented builds seeking an exhaust upgrade without changing unrelated engine systems.
Technical & Fitment Notes
- Confirm piping/tip configuration, emissions-equipment compatibility, and any trim or drivetrain-specific fitment notes for the exact HKS part number.
- Exhaust sound and cabin presence vary with the rest of the exhaust system, engine configuration, and vehicle modifications.
- Original catalog note: In the December 2005 issue Import Tuner Magazine, Import Tuner dyno tested the HKS Dual Hi-Power Ti Exhaust System for the Nissan 350Z. With no other modifications the HKS exhaust system produced peak horsepower and torque gains of 14HP and 7.0lb-ft, respectively. The exhaust averaged +11.8HP and +5.70lb-ft of torque across all dyno runs. Final power and torque output measured at the rear wheels with the HKS Exhaust were 243.6HP and 232.80lb-ft.

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restri
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
