Product Details

Part Number: 32003-BH001
Brand: HKS
Color: Silver
Size: 2.36 in (60 mm)

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.

HKS Hi-Power 04 SI
Brett | September 29th, 2023
Came fast & was a straight forward and easy install. Comes with a silencer & all the parts needed. 10/10 best sounding ep3 exhaust with good flow. No drone and sounds amazing with ZERO rasp and gives the K20 a good deep tone.
Great exhaust

I have a 2004 ep3 with dc sports headers and this exhaust sounds so good with it! Shifting from 1st to 2nd and to 3rd all high revs gives a slight pop, it's amazing to hear! Highly recommend!
Sounds Amazing!

Definitely made the right choice. Looks amazing and has Deep tones. definitely some of the best exhaust I've heard on a 4 cylinder engine. Much smoother through power band now also.
Good purchase

Gave me just what I was looking for. Not too loud, but certainly not quiet. Nice deep tones. I was worried it might sound fart boxy being that it was going on a Honda and we all know how bad they can potentially sound, but that was not the case with this hks. I'm happy as a clam.
