Subaru WRX STi Performance Exhaust - HKS - Super Turbo Catback - '14-'27. This HKS Super Turbo Muffler cat-back delivers a refined boxer tone and freer flow for daily use and spirited drives.

Engineered to balance low backpressure with sound control, this cat-back replaces the rear section while retaining the factory catalytic converters. Stainless steel construction and precision bends enhance durability and efficiency, while the large-canister muffler with integrated resonation tempers cabin harshness and preserves the signature rumble. Designed for a direct, bolt-on fit with factory-style hangers.

Features

• Cat-back layout retains catalytic converters
