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.
For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies. Depending on the application, Hi-Power muffler tips are 96mm, 115mm and 120mm in diameter, piping diameter ranges from 55mm to 95mm. Special Edition HKS Carbon Titanium Hi-Power Exhaust systems are exclusively available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping.

Hks hi powered exhaust
First time using a hks product and I’m very happy with it! Great quality exhaust and opened up the cars sound pretty good not too loud but you can definitely hear it when on the throttle even burbles a little bit. The tip is angled perfectly with the rear bumper and polished so it pops out! Side note you do have to cut off the old muffler so be prepared for that otherwise definitely worth the money

The best you can get
HKS is known as one of the best, if not the best JDM companies around for a reason. This exhaust fit 100% correctly the first time. Piping is 3", amazing craftsmanship, and hardware is included. It's actually deceptively quiet, but what you do hear has an amazing tone.

Quality Catback
With a catback, what you pay for is what you get, and this is no exception. This exhaust sounds better as time goes by, and is surprisingly quiet when you are driving normally. It's when you romp on it that lets people know you're not messing around with your minivan. If you want to gain power and sound great while doing it, this is the exhaust for you!
