GT-R33 HKS Hiper Muffler 31019-AN006

GT-R33 HKS Hiper Muffler Exhaust 31019-AN006 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-RPM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path. Code No. 31006-AN023 Cert. No. 03S14922 Vehicle SKYLINE GT-R Model BNR32 Engine RB26DETT Model Year 89/08 – 94/12 · Shape of muffler HP (Titan color) (Hi-Power) Main material S304 Diameter of tip 120 Diameter of center pipe 85(*1) Close noise level Stock 93 HKS 99 About road clearance(*2) Clearance 115mm Portion of the kit Center pipe Remarks Product Weight Remarks Make to order item About HKS muffler *1: About center pipe Diameter of center pipe is the portion that has the largest diameter. (Excluding silencer and tip.) It is the condition with stock suspension. *2: Minimum road clearance between HKS muffler (Any parts included in the kit) and road surface. Therefore, it may be different from actual road clearance of the vehicle. The data is basically the condition with stock suspension. However, please understand that some items have data with low down spring or ride height adjustable suspension kit. Caution: Hook, bracket, stay may be changed without prior notice. ★ Exhaust noise level at idle. 【Hi-Power】 HKS Hi-Power Muffler came back with the same concept, “High Power & High Performance”, and “Resonant Sound” and “Stylish” are harmonized together. High performance for stock to high performance vehicles with upgraded turbines, sound quality, are the JASMA standard are implemented together. This had been impossible in a long exhaust tuning history. To maintain the exhaust efficiency, enlargement of the exhaust pipe is usually required; the sound level tends to be increased and low-tone. The exhaust system with a cannon ball-shaped shell usually has lower silencer capacity than an oval-shaped shell; therefore, to reduce the sound level, the pipe diameter is narrowed. However, a narrow pipe diameter also reduces the exhaust efficiency and increase the exhaust pressure. HKS utilized original unique technology to maintain the exhaust capacity and sound level to meet the JASMA standard which is more severe than the regular safety standard. Inner structure of the silencer was redesigned so the unwanted low exhausts resonance was eliminated, and the sound quality was improved. Titanium Color Exhaust Tip Brightly shined titanium color tips are used for GT-R and Silvia. This tip is made of stainless (SUS304) which improve appearance and cost-performance. Exhaust Dress-up Evolution & Safety regulations applicable. Powerful rear view with the cannon ball-shaped & modern titanium color tips improve the appearance. Tuning cars race in circuits for a time attack have improved the appearance more stylish. To maintain large exhaust capacity, the pipe diameter of the exhaust pipe installed on the bottom of a vehicle must be enlarged, and the ground clearance must be narrow. HKS Hi-Power Muffler was designed to maintain sufficient ground clearance with redesigned flanges and layout. * Data is based on the test results of a prototype for RB26.
