TOYOTA GR SUPRA SZ-R exhaust system achieves unparalleled exhaust efficiency while meeting strict sound level standards.
Balance of Performance and Comfort
It combines a pleasant sports sound while suppressing an unpleasant drone. It is designed with a valve structure that allows the stock motor to be relocated. You will continue to be able to use the various mode switches as they are.
Complies with strict international noise standards
Complies with the noise regulation values of the UN Regulation No.51 Phase 2 with fitted on DB26. Reduced exhaust volume at cold start compared to the existing HKS Super Turbo Muffler for DB22 (89dB->82dB).
Product Features
Due to minor changes in the vehicle (DB22 to DB26), the vehicle now has to meet the stricter noise regulation of urban acceleration noise phase 2 (regulation value 71 dB). This is the only pre-certified exhaust for the DB26 that complies with the strict regulations. (As of 2023/11)
110mm diameter super turbo tail with inner slit is adopted for the tail.
A silencer added to the middle pipe reduces the overall sound volume, while sound tuning of the low frequency and suppressing drone, which is unpleasant in the daily drive, has been done to achieve a gentle sound.
The sound volume is 87dB compared to the stock 81dB, with a moderate bass sound at low RPM and a mid-to-high range as the RPM increases, allowing the driver to enjoy a sporty and clear sound.
For DB22, there are two choices: this product and the existing product (31029-AT005). If you prefer a low volume and want a refined sound, choose this product. If you prefer a more wild sound at high RPM, please choose the existing product.
