Fitment Information: This exhaust system is specifically designed for 2002 - 2007 Subaru WRX and 2004 - 2007 Subaru STI models. Features: The Carbon - Titanium Hi - Power is the upgraded version of the HKS Hi - Power catback. It comes with all the great features of the regular exhaust, like 75mm (3 - inch) straight piping, a resonator, non - tapered piping, and an angled - exit muffler. The standout feature is its carbon - fiber wrapped stainless steel muffler with a titanium tip and full SUS304 stainless steel piping. This exhaust reduces backpressure, thanks to its 3 - inch straight piping and free - flowing muffler. It boosts performance, giving your car more horsepower and torque, while also reducing turbo lag. The result is an aggressive, deep, and throaty exhaust note. Other features include a 4.72 - inch tip size, exhaust hangers welded onto OEM locations for easy installation, and it comes with a new gasket and hardware. Note: If you're using a stock j pipe or downpipe, you'll need to buy the GrimmSpeed Subaru Stock DP to Aftermarket 3 - inch Catback Adapter separately.
Using your HKS Carbon Titanium Cat Back Exhaust is easy. Just install it following the included instructions, as the exhaust hangers are welded onto OEM locations for a direct fit. Once installed, start your car and enjoy the improved performance and great exhaust sound. Here are some important notes: If you have a stock j pipe or downpipe, don't forget to buy the GrimmSpeed adapter separately. For maintenance, regularly check the exhaust for any signs of damage or loose parts. Keep it clean by using a mild soap and water solution. Avoid using abrasive cleaners that could scratch the carbon fiber or titanium parts. With proper use and care, this exhaust system will serve you well for a long time.
