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-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.
One of my big concerns before purchasing this exhaust was to ensure it was a dual exit system. I have seen some websites selling an HKS exhaust but only a single exit. I called and spoke with a customer service rep ( i believe his name was Daniel) and he personally walked over to the product and checked to ensure it was a dual exhaust system for me.
The sound is absolutely beautiful. My only complaint is the exhaust was touching my bumper on the passenger side, but with some maneuvering and yanking, it is no longer touching. Overall a great exhaust that you feel immediately after hitting the ignition.
