Akrapovic Performance Exhaust — S-TY/T/2

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Toyota GR and GRMN Yaris. Crafted entirely from lightweight, high-grade titanium, this system is designed to enhance every aspect of the driving experience—from sound and performance to weight savings and aesthetics. More than just an exhaust, it’s the finishing touch the Yaris deserves and how it should have come from the factory. With motorsport-inspired engineering and a focus on lightweight performance, this system sets a new benchmark for track-focused upgrades.

Sound

The Akrapovič Slip-On Race Line transforms the GR Yaris’s three-cylinder engine with a distinctive, race-inspired exhaust note. At the heart of the system, a cast titanium collector—crafted in Akrapovič’s in-house foundry—optimises and balances gas flow, creating a finely tuned acoustic experience free from droning. This design works in harmony with three precisely positioned resonators—two located behind the collector and one in the middle pipe—to deliver a deep, engaging tone that complements the engine’s character.

Engineers placed a special emphasis on acoustics across the rev range, ensuring a high-frequency tone at higher rpms and a more dynamic, pronounced sound during idle and revving. This enhanced sound profile is further shaped by twin megaphone-shaped titanium tailpipes, larger than stock at 110 mm, which amplify the sporty tone while adding visual impact. 

Performance

Inspired by its rally heritage, the Akrapovič Slip-On Race Line (Titanium) is engineered to optimise the GR Yaris’s performance while maintaining everyday usability. By reducing back pressure and enhancing exhaust flow, the system allows the three-cylinder engine to operate more efficiently, delivering sharper throttle response, stronger acceleration, and a more dynamic driving experience.

Akrapovič’s dyno testing confirms measurable gains, including a power increase of +12.9 hp and +9.6 ft-lb of torque at 6,950 rpm. Additionally, the system reduces weight by 4.7 kg, making it 37.4% lighter than the stock exhaust. These benefits improve agility, cornering precision, and overall handling—all achieved without the need for ECU remapping, ensuring seamless installation and compatibility with the factory setup.

For those seeking even greater performance, the optional Evolution Link Pipe (Stainless Steel) removes the OPF/GPF and further optimises exhaust flow. When paired with the Slip-On Race Line, it delivers combined gains of +18.4 hp at 5,900 rpm and +16.1 ft-lb of torque, alongside an additional weight reduction of 19.6%.

Design

This exhaust system combines functionality and aesthetics with Akrapovič’s signature engineering precision. Constructed entirely from race-proven, high-grade titanium, the system features twin megaphone-shaped tailpipes that are specially coated to resist discoloration from high heat, ensuring durability and a visually striking appearance. At its core, a cast titanium collector optimises gas flow, enhancing both the exhaust note and overall performance. Every detail of the Slip-On Race Line reflects Akrapovič’s dedication to engineering excellence, delivering a system that seamlessly combines high-performance functionality with a design that complements the GR Yaris's rally-inspired character.

Modern exhaust regulations often restrict the true character of performance cars, but Akrapovič’s Slip-On Race Line (Titanium) brings the Yaris GR and GRMN to life. With its lightweight titanium construction, thrilling sound, and race-proven performance, this system is the ultimate upgrade for track enthusiasts. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
