Grimmspeed Gentleman’s Resonated Catback 2013-2025 BRZ / FRS / 86 | Refined Deep Tone | Performance Exhaust System
Overview
The Grimmspeed Gentleman’s Resonated Catback exhaust system is designed specifically for the Subaru BRZ, Toyota 86, and Scion FR-S models from 2013 to 2025. This catback exhaust enhances the driving experience by delivering a mature, balanced exhaust note that complements the naturally aspirated FA platform. It’s ideal for enthusiasts who want a deeper, more aggressive sound without the excessive volume or drone that can detract from daily driving comfort.
Engineered with precision, Grimmspeed’s approach focuses on a full 3-inch stainless steel flow path with straight-through resonator and muffler designs. This ensures minimal restriction and maximizes exhaust flow while carefully tuning the sound signature to reduce cold-start harshness and highway drone. The system’s symmetrical axle-back layout and proprietary glass fiber muffler packing contribute to a refined tone that respects the car’s balanced chassis and lightweight nature.
For Subaru BRZ and Toyota 86 owners, this exhaust system strikes the perfect balance between performance and refinement. It enhances throttle response and exhaust note without overwhelming the cabin, making it suitable for both spirited driving on back roads and comfortable daily commuting. The Grimmspeed Gentleman’s Resonated Catback is a thoughtful upgrade that respects the platform’s driver-focused character while delivering a noticeable improvement in sound and flow.
