Product Description

The HKS 31021-KN001 Legamax Premium Catback Exhaust is a high-performance aftermarket exhaust system specifically designed for the 2009-2021 Nissan GT-R R35 AWD equipped with the VR38DETT engine. Built with flux-welded SUS304 stainless steel and featuring a substantial 85 mm main pipe and quad large-diameter tips, this exhaust improves exhaust gas flow and reduces backpressure over the stock system, resulting in enhanced throttle response and broader power delivery. The quad burnt titanium style tips give the rear of the car an aggressive and refined look that complements the GT-R's performance heritage.

This Legamax Premium system bolts directly onto the factory mounting points with included hardware and gaskets, making installation straightforward for qualified installers or experienced enthusiasts. Its sound profile delivers a sportier exhaust note without excessive interior drone, making it suitable for both spirited driving and daily use. Engineered by HKS with performance and durability in mind, this exhaust is a popular upgrade for GT-R owners seeking a balance between power, sound, and build quality.
