HKS Hi-Power Muffler SPEC-L Catback Exhaust System - 2013-2021 Scion FR-S / Toyota 86 / Subaru BRZ

Looking to add a quality exhaust note to your FR-S, BRZ, or 86 without sacrificing fitment or refinement? The HKS Hi-Power Muffler SPEC-L is a lightweight performance exhaust designed to deliver a sportier sound, improved exhaust flow, and reduced weight compared to the factory system.

HKS is known for building high-quality exhaust systems that balance sound, performance, and durability. The SPEC-L uses 2.5" 304 stainless steel piping with smooth bends to improve flow, helping the FA20 breathe better while adding a more aggressive tone that still feels appropriate for a street-driven car.
