HKS Toyota GR Yaris GXPA16 Gen2 Super Turbo Muffler

The HKS GXPA16 Gen2 Super Turbo Muffler is built with a unique dual-chamber design that HKS has refined over years of performance tuning. This muffler isn't just about making noise; it's engineered to manage exhaust flow efficiently, which is crucial for a high-performance car like the GR Yaris. The internal baffling is carefully crafted to reduce backpressure while still providing a satisfying, sporty exhaust note that complements the car's character without being overwhelming.

Constructed from SUS304 stainless steel, this muffler is well-built to withstand the rigors of daily driving and spirited track use. The material choice ensures excellent corrosion resistance, meaning it will hold up well against road salt, moisture, and varying temperatures. HKS has focused on a design that offers an improved exhaust flow compared to the stock unit, aiming to unlock a bit more power and responsiveness from the 1.6L G16E-GTS engine. The Gen2 version incorporates updated internal structures based on HKS's extensive testing and feedback from the GR Yaris community, aiming for an even better balance of performance and sound.

Installation of this cat-back muffler is designed to be a direct replacement for the factory unit, utilizing the original mounting points. While it's a bolt-on part, proper alignment and securing of all connections are important for optimal performance and to prevent any exhaust leaks. This muffler is a significant upgrade for GR Yaris owners looking to enhance their vehicle's exhaust system for both sound and performance, reflecting HKS's long-standing reputation in the tuning world.
