HKS Super Turbo Muffler | 207.6/5310 | 427.3/2600-4500 |

Super Turbo Muffler: 31029-AT009 with Stock ECU
Stock Exhaust:Stock Exhaust + Stock ECU
Since the stock ECU manages output by boost and torque, peak output will be suppressed to the stock value only by replacing the exhaust, however the improved exhaust efficiency of the exhaust makes it easier to extend the RPM from the peak output.

Super Turbo Muffler:31029-AT009 with HKS Mastery ECU
Stock Exhaust :Stock Exhaust + HKS Mastery ECU
Combined with HKS Mastery ECU, the power output peak is increased by approximately 5.6 kW. Peak torque output has also been improved by approximately 13.5 Nm, and the maximum difference is a significant 18.5 Nm. By tuning together with the ECU as well as replacing the exhaust, it is possible to increase the power output compared to the stock exhaust.
*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.
