Product Highlights

• Legendary FGK Engineering & Sound: Manufactured by Fujitsubo Giken Kogyo (FGK), this system guarantees exceptional build quality, optimized exhaust flow, and a deep, aggressive yet refined tone that enhances the driving experience without excessive drone.

• Exclusive Integration with GR × GROW Design Diffuser: This exhaust is specifically engineered to pair perfectly with the GR × GROW Design rear diffuser. It cannot be installed with the factory diffuser or other aftermarket diffusers, ensuring a seamless, flush-mounted fit and a cohesive, purpose-built appearance.

• Premium SUS304 & Titanium Construction: The main body is crafted from high-grade SUS304 stainless steel for superior corrosion resistance and longevity. It features 92mm diameter titanium tailpipes that add a striking visual highlight and reduce weight at the rear.

• Complete with Valve Canceller: The kit includes a genuine muffler valve canceller, allowing for a consistent exhaust note and performance character by bypassing the factory valve system. This ensures the full sound and flow potential of the FGK system is always active.
