MIA's Description

The HKS Legamax Premium Axle-Back Exhaust (PN: 31021-AF021) is designed for the Subaru WRX STI Sedan (GVF, EJ25 Turbo, 2010-2014) to enhance performance and sound. It delivers a sporty tone that is quiet in the cabin but aggressive under acceleration. This axle-back system includes the main silencer and main pipe, allowing for direct bolt-on installation to the factory midpipe. Constructed from durable 304 stainless steel, it features 90mm burnt quad tips and a 54mm center pipe diameter.
