Product Description

The **HKS 31008-KN002 Racing Muffler w/ Silencer Exhaust System** is a high-flow cat-back performance upgrade engineered for the Nissan GT-R R35 equipped with the VR38DETT twin-turbo V6 engine (2007-2024). Designed with racing specifications in mind, this system targets ultra-high output applications exceeding 1000 PS, reducing exhaust backpressure with a large 101.6 mm main pipe and an exclusive post-secondary-catalyst routing that eliminates restrictive stock flanges.

Constructed from durable SUS304 stainless steel and featuring four large 124 mm tips, the system delivers an aggressive exhaust tone that's tuned for performance without becoming unbearably loud. The integrated silencer version helps balance sound quality while maintaining strong flow characteristics. Direct bolt-on installation ensures compatibility with OEM mounting points, though users should note that ground clearance is approximately 15 mm lower than stock. Ideal for high-power builds, track-focused GT-Rs, and tuned engines, this HKS racing muffler exhaust provides enhanced performance and an unmistakable exhaust note for serious enthusiasts.
