Catback Exhaust for Subaru BRZ (2013-2016) 2.0L

High-Flow Catback Exhaust System for 2013-2016 Subaru BRZ

What it Does: The Catback Exhaust System replaces the restrictive factory exhaust piping and baffled muffler on the 2013-2016 Subaru BRZ to reduce exhaust backpressure, improve exhaust gas scavenging, and deliver an aggressive boxer exhaust note.

The Stock Subaru BRZ Exhaust Restriction

The factory exhaust on the ZC6 chassis utilizes narrow-diameter piping with restrictive crush bends and a heavy, baffled rear muffler assembly engineered solely for sound suppression. This internal design creates excessive parasitic backpressure downstream of the front pipe, exacerbating the notorious midrange torque dip common to the naturally aspirated FA20 engine between 3,200 and 4,500 RPM. Additionally, the OEM aluminized steel is prone to surface corrosion and flange degradation over multiple thermal cycles.

The Engineering Solution

Engineered as a direct bolt-on replacement, this performance system is fabricated from mandrel-bent T304 stainless steel to maintain a constant inner diameter and eliminate flow turbulence. Featuring precision TIG-welded joints, thick CNC-machined connection flanges, and pre-welded OE-style hanger positions, it ensures an airtight seal and leak-free installation without custom fabrication. The straight-through, sound-attenuating muffler configuration optimizes exhaust pulse velocity and thermal heat dissipation, producing a crisp, drone-free exhaust profile under heavy load.
