02-07 WRX & STI HKS Exhaust Systems

HKS Hi-Power Catback

The HKS Hi-Power WRX & STI Catback Exhaust features 3" coated mild steel piping and a stainless steel angled-exit Hi-Power muffler for true JDM look and sound. The HKS Hi-Power's full straight, 3" piping and free-flowing muffler with 4.75" tip reduce back pressure and create significant performance gains while giving your WRX or STI a deep, throaty exhaust tone.

HKS Carbon Titanium

The "bling-bling" version of the HKS Hi-Power catback, the Carbon-Titanium Hi-Power has all the features of the regular exhaust: 75mm piping, a resonator, non-tapered piping, and an angled-exit muffler, but, as the name implies, the Carbon Titanium features a carbon-fiber wrapped stainless steel muffler with a titanium tip and full SUS304 stainless steel piping. The HKS Hi-Power Carbon Titanium's full straight, 3" piping and free-flowing muffler reduce backpressure and create significant performance gains while giving your WRX or STI a deep, throaty exhaust tone.

HKS Sport Catback

The Sport Exhaust system is perfect for those who daily their cars and don't want anything too loud or obnoxious. It is constructed of ceramic coated mild steel 75mm piping with a 106mm tip. This system will add performance and a great stealth look for your WRX or STI but will not catch unwanted attention like most aftermarket systems. All hardware and gaskets are included for install.

HKS Titanium Catback Exhaust

For high horsepower 02-07 Subarus, HKS now offers the Racing Titanium Muffler system. Constructed of high-luster polished SUS304 stainless steel 3" piping and a 170mm titanium muffler assembly, the Racing Muffler is the lightest system (40% lighter than the race inspired Hi-Power Exhaust system) and the highest flowing exhaust system HKS offers. The muffler utilizes a slip-on/latch design that mates polished stainless steel piping and a lightweight titanium Muffler assembly.
