Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power cat back 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-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path. 

This HKS Lancer Evolution 8 30th anniversary full 304 stainless steel Cat back exhaust system has 120mm tip and 75mm pipe diameter.
