AKRAPOVIC SLIP-ON RACE LINE (TITANIUM) - TOYOTA GR YARIS 2021 - 2022 SKU: S-TY/T/2

Here are the advantages of the Akrapovič Slip-On Race Line (Titanium) – SKU: S-TY/T/2 exhaust for the Toyota GR Yaris (2021-2022), based on what the manufacturer and independent sources report. 

Key Advantages

1. Weight Reduction
   
• The titanium construction of the Slip-On Race Line makes it significantly lighter than the stock exhaust. One source says ~4.7 kg lighter, which is about 37.4% weight saving over the original exhaust.  
• Less weight helps in agility, quicker response, better handling—especially in corners. Lower unsprung and total mass tends to improve acceleration, braking, and steering response.
2. Performance Gains
   
• On a dyno, this exhaust provides measurable increases: approx +12.9 hp and +13 Nm (or +9.6 ft-lb) of torque around 6,950 rpm when compared to the stock system.  
• If paired with the optional Evolution Link Pipe (Stainless Steel), even greater gains are claimed: as much as +18.4 hp and +16.1 ft-lb torque at around 5,900 rpm.  
3. Improved Sound / Acoustics
   
• More aggressive, motorsport-inspired exhaust note. Deeper tone at idle / lower revs, sharper and more high-frequency tone at higher revs.  
• Designed to minimise undesirable drone: thanks to multiple resonators (two behind the collector, one in the middle pipe), and an optimised cast-titanium collector.  
4. Aesthetic Quality & Durability
   
• High-grade titanium parts with megaphone-shaped titanium tailpipes that are larger than stock (~110 mm) and coated to resist discoloration from heat.  
• Premium build quality: Akrapovič foundry castings (collector), good finish, precision engineering.
5. Bolt-On / Compatibility Aspect (with some caveats)
   
• The product is designed to integrate with the existing exhaust layout; many sources say no ECU remapping needed for the basic Slip-On system. That means easier installation without needing to alter engine management software for decent gains.  
• Warranty support: Akrapovič gives a 2-year product warranty.  
6. Track & Motorsport Feel
   
• Because of its materials and design, this exhaust gives more of a track/ motorsport vibe — both in sound and performance. If you use the car in more spirited driving / track days, the exhaust better matches the car’s sporty capability.
