This is the HKS entry level exhaust for the Supra, which is very similar with the APEXi N1. This exhaust exits out the car at a slight angle, which helps minimize bends and creates one of HKS best flowing exhaust system's to date.



This system has a 115mm tip with 75mm piping. Inspired by & designed from the N-1 Endurance Race series in Japan, HKS has deverloped its Hiper Exhaust systems for both turbocharged & normally-aspirated vehicle applications. Each Hiper system is constructed using an unchamber (SUS 304) stainless steel muffler assembly, high-quality computerized welds, & large diameter ceramic-coated steel piping. Unlike the straight-back design of the Drager systems, Hiper mufflers & tips feature a unique offset flow & mounting design.

On a scale of 1-10 with 10 being the loudest exhaust and 1 being the factory exhaust sound, the HKS Hiper (basic) comes in at around a 6.
