Product Description

The HKS 32018-AF017 LEGAMAX Premium is a direct-fit axle-back exhaust for the 2019-2024 Subaru Forester SK9 (2.5L FB25) and SKE (2.0L e-Boxer hybrid). Engineered with a full straight-through internal structure and optimized pipe layout, the system achieves a 50% reduction in exhaust backpressure compared to stock. The rear view is transformed by dual 90mm titanium-finish tips positioned on both sides of the bumper, replacing the stock hidden exhaust outlets with a sporty dual-exit appearance.

Built from S304 stainless steel, the LEGAMAX Premium raises close-proximity sound from 77 dB to 86 dB and idle sound from 52 dB to 57 dB. Does not fit the 4BA-SK5 (1.8T turbo) chassis or the 2025+ SL-generation Forester. Sold as one complete rear section. Made in Japan by HKS.
