Race-Proven Titanium Slip-On Exhaust Built for the Toyota GR Yaris on Track
The Akrapovic S-TY/T/2 Slip-On Race Line Exhaust System delivers serious performance gains for the 2021-2023 Toyota GR Yaris on closed-circuit and race track applications. Constructed entirely from race-proven titanium, the S-TY/T/2 adds +9.5 kW at 6,950 rpm and +13.0 Nm of torque while cutting system weight by 4.7 kg, a 37% reduction versus stock. Megaphone-shaped 110mm titanium tailpipes and a triple-resonator design produce an aggressive, acoustically tuned race sound without drone. No ECU remapping is required, though the factory exhaust must be cut during installation. For customers seeking further tuning capability, an optional Evolution Link Pipe is available.

Frequently Asked Questions
Is the Akrapovic S-TY/T/2 street legal for the Toyota GR Yaris?
No. The S-TY/T/2 is designed for race track and closed-circuit use only. It does not meet road-use emissions compliance requirements. It is intended for competition and track-day applications.
Does installing the S-TY/T/2 require cutting the factory exhaust?
Yes. Installation of the S-TY/T/2 requires cutting the original factory exhaust system. This is a permanent modification. No ECU reprogramming is required for this slip-on configuration.
Does the Akrapovic S-TY/T/2 require an ECU remap?
No ECU remapping is required for the slip-on S-TY/T/2 configuration alone. However, customers who add the optional Evolution Link Pipe for further tuning capability may benefit from additional ECU tuning to fully optimize power delivery.
What are the verified power and torque gains for the S-TY/T/2?
Testing conducted on the Akrapovic dynamometer showed gains of +9.5 kW (12.9 hp) at 6,950 rpm and +13.0 Nm of torque at 6,950 rpm versus a GR Yaris equipped with the factory exhaust system.
How much weight does the Akrapovic S-TY/T/2 save versus the factory exhaust?
The S-TY/T/2 system weighs 7.8 kg and saves 4.7 kg versus the factory exhaust, representing a 37% weight reduction. This reduction improves the vehicle's power-to-weight ratio and reduces unsprung rear mass.
What is the diameter of the S-TY/T/2 tailpipes?
The megaphone-shaped titanium tailpipes measure 110mm in diameter, larger than the factory units, reducing exhaust back-pressure and contributing to both the power gains and the aggressive race sound character.
What year GR Yaris does the S-TY/T/2 fit?
The S-TY/T/2 fits the 2021-2023 Toyota GR Yaris (pre-facelift generation). For the 2024+ facelift GR Yaris, Akrapovic offers a separate Slip-On Race Line system (S-TY/T/3).
Is there an optional link pipe available for the S-TY/T/2?
Yes. Akrapovic offers an optional Evolution Link Pipe for customers who want to extend the tuning range of the S-TY/T/2 system for improved performance beyond the slip-on configuration alone.
What makes the sound of the S-TY/T/2 unique?
The S-TY/T/2 uses three resonators (two positioned at the rear of the in-house cast titanium collector and one in the mid-pipe) to produce an acoustically tuned, sports race sound profile while eliminating interior drone at cruise speeds.
Does the Akrapovic S-TY/T/2 come with a warranty?
Akrapovic exhaust systems are backed by the manufacturer's limited warranty when installed correctly and used as specified. As a race-only product, warranty coverage applies to track and closed-circuit use per Akrapovic's terms. Contact Black Ops Auto Works for full details.
