Burn Axle Back Muffler For Subaru BRZ (2012-2020)

Unleash the FA20 Boxer Growl: Burn Axle Back Muffler for Subaru BRZ, Scion FR-S, & Toyota 86

Who Is This For? Designed specifically for Scion FR-S, Subaru BRZ, and Toyota 86 owners running the FA20D / 4U-GSE Boxer engine who are looking for a competition-ready sound and reduced weight for track use.

The Muffled Boxer Syndrome: From the factory, the 2.0L Boxer engine is hidden behind a massive, heavy "suitcase" style muffler that stifles the engine’s natural acoustic character and restricts exhaust flow at high RPMs. You step on the throttle coming out of a corner, and instead of a crisp, mechanical roar, you get a muted hum that feels disconnected from the driving experience. This restrictive factory setup creates unnecessary backpressure and adds dead weight to the rear of your chassis.

The Engineering Solution: We engineered this Burn Axle Back system to delete the restrictive factory baffles and replace them with a high-flow, straight-through design. Utilizing 2.50" OD stainless steel piping and massive 4.50" slanted tips, this kit allows your FA20 engine to breathe freely while shedding significant weight compared to the OEM assembly. It is a direct-fit solution designed for off-road competition and racing, ensuring your car sounds as fast as it looks on the circuit.

The Comparative Edge: Why This Beats the Competition

• The Visual Impact: Features a premium "Burn Finish" on double-walled tips, providing a high-end racing aesthetic that resists the dulling found on cheaper, single-walled chrome alternatives.
• Superior Material Grade: Constructed from high-quality Stainless Steel with heavy-duty 3/8" flanges to prevent warping under high-heat track conditions, unlike thin-gauge aluminized steel that corrodes after a single season.
• Precision Flow: The 2.50" OD piping is optimized for the FA20’s displacement, providing the perfect balance of exhaust velocity and volume without the "drone" common in un-engineered universal mufflers.
