Axle Back Exhaust for Subaru BRZ (2022-2024) 2.4L

High-Flow Axle-Back Muffler Delete Exhaust for 2022-2024 Subaru BRZ (ZD8)

What it Does: The axle-back muffler delete exhaust replaces the restrictive factory rear muffler on the 2022-2024 Subaru BRZ to reduce vehicle weight, lower exhaust backpressure, and amplify the boxer engine tone.

The Stock Subaru BRZ Exhaust Restriction

The factory ZD8 exhaust incorporates an oversized, multi-chambered transverse muffler weighing upwards of 26 pounds directly behind the rear axle line. This design induces acoustic damping and parasitic backpressure while adding dead weight to the car's polar moment of inertia. Furthermore, the baffled internal passages stifle the distinct firing cadence and exhaust velocity of the 2.4L FA24D boxer powerplant.

The Engineering Solution

Constructed from mandrel-bent 304 stainless steel, this straight-through axle-back replacement eliminates internal acoustic restriction, establishing an uninterrupted exhaust gas exit path. High-integrity TIG welds resist thermal cycling and vibration fatigue, while integrated mounting prongs match OEM rubber isolator positions. By deleting the bulky silencer and utilizing a dual-exit layout with integrated tips, this setup minimizes flow turbulence, significantly sheds rear overhang mass, and bolts directly to the factory mid-pipe flange.

What's Included

• Pair of 304 stainless steel axle-back exhaust pipes with tips
• Mounting hardware kit

Frequently Asked Questions & Fitment Warnings

Does this fit the ZD8 BRZ?

Yes, this is a direct fit for the 2022-2024 Subaru BRZ equipped with the FA24D 2.4L engine. Does not fit first-generation 2013-2020 ZC6 chassis models or non-2.4L engine configurations.

Is an ECU tune required after installing this axle-back?

No, an ECU recalibration is not required because this exhaust system installs downstream of the catalytic converters and factory oxygen sensors, leaving air-fuel ratios unaffected.

The Subaru Performance Standard

Engineered for pure JDM sports coupe balance, this exhaust component enhances high-RPM pulse scavenging and unleashes raw boxer acoustic feedback without compromising road durability.
