  • By shifting the Super Turbo Muffler to a lightweight material, titanium, this product weighs approx. 9.2kg whereas the stock exhaust weighs 12.4kg, achieving a weight reduction of approx. 26%.

  • We newly adopted an optimally shaped mid silencer and Y-pipe prior to developing the Super Turbo Muffler with titanium material.

  • Compared to the stock exhaust with pipes diameter of 70mm ⇒ 60.5mm ⇒ 42.7mm x 2 and a separation wall structured silencer, this product achieves overwhelming exhaust performance by adopting pipes diameter of 74.7mm 60.5mm x 2 and a straight structured silencer without restrictions.

  • Sound tuning, including the use of a silent chamber and optimization of the silencer, has reduced unpleasant drone and enhanced a unique titanium exhaust sound.

  • While retaining the signature silted tails of the HKS Super Turbo Muffler, the titanium tail with the HKS logo engraved and matte finish with burnt titanium blue is featured.  

 

 

Exhaust Resistance

 

  • The above graph shows how flow rate is related to pressure, measured on a flow bench. The lower the pressure relative to the flow rate, the lower the exhaust resistance.
  • By adopting a pipe diameter of 74.7mm ⇒ 60.5mm x 2 and a silencer without restriction, the exhaust resistance of this product is reduced by about 70% compared to the stock exhaust. (Comparison at a flow rate of 200L/sec)         

 

 

Results of Power Check

 

  • The replacement of the exhaust improved maximum output and torque, especially in the mid-range torque output and high RPM power output.
  • Power output improved by about 8.1% at the point of greatest difference, maximum power output increased by about 3.1%, torque output improved by about 5.6% at the point of greatest difference, and maximum torque output improved by about 1.2%.

 

 

Sound Characteristics

 

  • The above graph shows the distribution of the maximum value of each frequency when measuring the proximity exhaust noise of the stock exhaust and this product.
  • The sound has been tuned to provide a powerful sporty sound while the silent chamber keeps the sound from becoming unpleasantly droned in the daily use rpm range.
  • For the mid and high frequency range, sound tuning was performed to make the titanium's unique sound characteristics stand out even more, and to create a pleasant sound when stepping on the gas pedal.
  • When combined with METAL CATALYZER (33005-AT011), the noise level is 90dB (idling volume 69dB) (☆2) compared to the Japanese exhaust noise regulation value of 96dB, so you can use it with peace of mind. (☆2 In-house measured value)

 

Remarks

・Not available for RS grade (1.5L FF). ・There is no effect on the minimum ground clearance with the installation of the product. (Vehicle minimum ground clearance: 118mm at the front subframe) ・Not compatible with vehicles equipped with GR rear bumper spoiler. ・Unqualified for Japanese exhaust noise regulation for GRMN Yaris (due to excessive sound level at acceleration). ・Not compatible with facelifted models after March 2024.

 

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.
