HKS Hi-Power Spec R Exhausts Specifications

In the Japanese vehicle category, HKS is a brand that is highly recommended, with almost 40 years experience in engine tuning, unparalleled by the competition.

The fruit of many years of engineering, HKS exhausts have undergone many demanding tests in order to offer reliability, performance, quality, great sound and finish, all of which are far superior to OEM parts. Easy to install with "plug & play" and bolt-on capacities, HKS exhausts can be installed without making any modifications.

The HKS Hi-Power Spec R range has been developed without compromise for enthusiasts seeking maximum exhaust performance. Every detail, from the overall design and manufacturing quality to the exhaust note and finishing, has been carefully engineered to meet the demands of high-performance driving while maintaining a sound level suitable for street use.

In the pursuit of ultimate efficiency, HKS employs a one-piece design that minimizes joints and flow restrictions, allowing the exhaust gases to follow the straightest and smoothest path possible. This advanced architecture optimizes engine efficiency, improves throttle response, and delivers outstanding performance throughout the entire rev range.

Constructed entirely from titanium, the Hi-Power Spec R cat-back exhaust system offers exceptional weight savings while providing outstanding resistance to corrosion and extreme temperatures. Depending on the application, its lightweight design can reduce weight by up to 65% compared to the factory exhaust system, contributing to improved vehicle dynamics. Combining ultra-lightweight construction, durability, premium build quality, and a distinctive sporty exhaust note, the Hi-Power Spec R is one of the most advanced exhaust systems in the HKS lineup.

All bolts and gaskets are included with the kit, facilitating installation. All HKS parts go in place of the OEM components without any modifications.
