HKS Performance Exhaust System

Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race-inspired offset muffler and piping design into many street applications, which offers a greater flow and higher RPM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.

FAQ

Will I need a tune with this exhaust?
Not required — a cat-back alone doesn't change anything the ECU needs to compensate for. But combined with intake and header mods, a tune unlocks the package — grab the N1 tune for your chassis: VersaTuner N1 Tune for the NC MX-5 / VersaTuner N1 Tune for the ND MX-5.
