| Single | 133.3/6900 | 187.4/6000 |
*This product changes the peak torque rpm compared to the stock exhaust.
It delivers superior performance across the entire rev range compared to the stock exhaust. For track purposes, you will benefit from the increased power at high RPM.

| Single (GT manifold) | 133.9/6900 | 191.9/6600 |
The torque dip between 3,500 RPM and 4,500 RPM can be prevented by installing the GT manifold (HKS manifold), resulting in improved peak power and torque.

●Weight
Weight Comparison
- Overwhelming weight reduction! 45% of the stock weight!!
HKS exhaust weight：7.8Kg
Stock exhaust weight：17.5kg
*The lightest stainless steel exhaust with a mid-pipe. (October 2024, according to HKS)
*The weight of the stock exhaust includes the mid-pipe.
Thickness of each pipes
- Main Silencer 0.5mm
- Mid Silencer 0.6mm
- Main Pipe 0.8mm T:1.2mm material is used in some areas where strength is required.
- Tail Tip：Inner Pipe 0.8mm
Outer Pipe 1.0mm (Titanium material)
*This exhaust is designed to be lightweight, so thin materials are used for each part. Although we have confirmed the durability of the exhaust, there is a possibility of deformation or damage if it is subjected to external force due to interference with the road surface or bumps, etc.
●Comparison w/o Sound Creator®
What is the Sound Creator® ?
The Sound Creator® is an OEM component attached to the suction pipe that amplifies intake sounds into the cabin.
What happens if you remove it?
Removing it will enhance the quietness inside the cabin, allowing you to enjoy a clearer exhaust note.
*Frequency (Hz) is a unit that represents the pitch of a sound; the larger the number, the higher the sound
A significant difference around 315 Hz impacts cabin quietness. Simply insert the included plug to silence the Sound Creator®, and you can enjoy a clearer exhaust note.

Conditions：Equipment other than the exhaust is stock parts (2000rpm to 4000rpm)
*Recorded inside the cabin.
*Peak values between the 2000rpm to 4000rpm.
*In-house measurements; results may vary.
*Sound Creator® is a registered trademark of MAHLE Filter Systems Japan Corp.
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.
