HKS Super Turbo Muffler is now available in the sophisticated URBAN MATTE EDITION
The matte-finished “Urban Matte” tail retains the chilly and rugged texture of the metal while shining softly and elegantly.
The matte finishing applied even to the inside of the tail, combined with the inner slit processing, gives it a sophisticated appearance.
The detailing of the exhaust parts is proof of HKS' passion and commitment to its products, which have been developed over a long period of time.

High quality exhaust with “low exhaust pressure” and “gentle sound”
While achieving “low exhaust pressure,” which is the basic performance required of the turbocharged vehicle exhaust system, it also suppresses the unpleasant drone sound in the common use RPM The comfortable sports sound will take you through the city streets. Of course, this is a vehicle inspection-compliant product that meets strict Japanese domestic noise standards.
Urban Matte Edition, where HKS’ master craftsmanship lives on.
”Super Turbo Muffler URBAN MATTE EDITION” is only allowed to be made by a very small number of craftsmen who have mastered outstanding welding techniques.
The careful handcrafting of each piece by these master craftsmen guarantees the ultimate in performance, combining durability and beauty.
The laser-engraved HKS logo on the tail is an elegant, deep color that completes a cozy look.
Comparison of Layouts (for 2.0Ｌ)
・31029-AT015 3BA-DB26/DB22
-
The stock exhaust has a silencer between the middle section, but the HKS muffler eliminates the middle silencer and extends the pipe length of the middle pipe to provide a sound tuned for a more uplifting sound in the mid-high range.
・Toyota Stock Exhaust for 2.0L trims
- Pipe size is D70mm, but is flattened in some parts.
- The pipe layout is a single layout unlike the HKS exhausts.

STM: SUPER TURUBO MUFFLER MATTE 31029-AT015 +STOCK ECU
STOCK: TOYOTA STOCK EXHAUST + STOCK ECU
Since the stock ECU manages power output by boost pressure and torque output, peak output will be limited to the stock value if only the muffler is replaced, but the improved exhaust efficiency of the muffler will make it easier to extend RPM from peak power output.

STOCK: TOYOTA STOCK EXHAUST + HKS Mastery ECU 42019-AT004
In combination with HKS Mastery ECU, the power peak increased by approx. 5.6kW compared to the stock. The torque peak was also improved by approx. 13.5Nm, and the max. gap is greatly improved to 18.5Nm. By not only replacing the exhaust, but also tuning together with HKS ECU, it is possible to improve the output easily more than with the stock exhaust.
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.
