"High-dimensional Super Turbo Muffler Debut"

Exhaust Efficiency & Sound Pressure Reduction are implemented together.

• Effective on stock to high performance vehicles w/ upgraded turbines.
• The performance exhaust sound meets the JASMA standard.
• Unique exhaust sound designed specifically for the engine.

“High-Dimensional Super Turbo Muffler Debut”
The essence of technology that combines Exhaust Efficiency and Sound Pressure Reduction.

D60.5 mm x 2 Full Dual Layout

While the stock layout has a pipe diameter of D45 mm x 2, this product has a full dual layout with a pipe diameter of D60.5 mm x 2.This allows a pipe cross-sectional area equivalent to D85 mm to be secured while lowering to the minimum ground clearance, which is often seen with high output mufflers. Exhaust pressure is reduced by around 40% compared to the stock model. This layout is designed for both daily use and performance.

Balance of steady-state comfort and sportiness

The silencer structure has been optimized and a silent chamber has been adopted to eliminate the unpleasant muffled sound in the steady state range. Once you step on the pedal, you can enjoy the sporty sound of the high-power V6 engine.

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.
