The Perfect Balance of Tone and Craftsmanship
The GrimmSpeed Axle-Back Exhaust transforms the sound and character of your 2022-2025 GR86 or BRZ while preserving the everyday comfort you love. Designed as a direct replacement for the OEM muffler, this system delivers the clean, confident tone enthusiasts crave; deeper at idle, fuller under throttle, and perfectly civil on the highway.
Every exhaust that wears the GrimmSpeed name carries our commitment to precision fitment, premium materials, and long-term reliability. We don’t cut corners, and we don’t settle for generic bends or off-the-shelf components. Each system is built from welded 304 stainless steel, mandrel-bent with custom geometry to maintain smooth exhaust flow and optimal clearance.
At the tail end, two 4-inch polished tips complete the look with a purposeful finish that mirrors the car’s athletic design. A laser-etched GrimmSpeed logo plate proudly reminds you that every inch of this exhaust was engineered, tested, and built the GrimmSpeed way.
Engineered for a Perfect Fit
Installation is straightforward thanks to our custom die-cut graphite compression gasket, developed specifically for the OEM stamped steel mid-pipe flange. This thicker design compresses evenly for a leak-free, lasting seal, unlike the thin multi-layer steel gaskets commonly used elsewhere. The result is an exhaust that fits flawlessly, sounds incredible, and lasts for years of driving.
