Will It Fit Your Vehicle?
Inspired by GT racing in Japan, HKS developed its Hi-Power catback exhaust system with features found on racing exhaust systems. The HKS Hi-Power catback exhaust series incorporates a race inspired offset muffler and piping design, eliminating unnecessary bends for the straightest exhaust path. This less restrictive design allows the HKS Hi-Power catback exhaust to have greater exhaust flow and less back-flow pressure, enhancing higher-PRM power gains.
The HKS Hi-Power catback exhaust system can be used for both turbocharged and naturally aspirated car applications. 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 HKS Hi-Power applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler.
Like the HKS Drager catback exhaust systems, the HKS Hi-Power catback exhaust systems are made from high-quality SUS304 stainless steel. Each HKS Hi-Power catback exhaust system features high-quality mandrel bent piping and application specific muffler assemblies.
Most HKS Hi-Power exhaust systems are complete catback units, which do not effect emission related hardware. Each HKS Hi-Power catback exhaust system is designed for a specific car application and can be bolted on out of the box, using factory mounting hangers.

Easy to install, other than removing the bolts on the cat. The sound is deep and there is some drone but it's not unbearable by any means. I felt more of a punch at the top end over the 2 1/4 straight pipe that I had before. I love the look of the exhaust with the can angled out at the back. I highly recommend this exhaust to anyone looking for good power and a great sound.

excellent exhaust. performance gains in the low to mid-range is decent, but in the high's is where it really shines. you can feel a good difference from stock exhaust to this when you WOT it. sound is amazing as well, although mine is VERY loud compared to my other friend with same exhaust, reason being that i have a test pipe. best exhaust imho for the ep3... or for any k-series motor for that matter!
