HKS have designed the High Power Exhaust for specific vehicle models to optimize the straightest flow pipe according to vehicle. Optimized piping for each vehicle model to ensure the straightest flowing piping possible. Enjoy the full sound of the engine with increased piping diameter, up to 3.5 inches. Very competitive pricing due to the use of SUH409 piping.

Feature:

• The weight of this stainless steel SPEC-L II is 9.4kg which is only 52% of the 19.3kg stock muffler.
• This lightweight system is realized through careful reduction of weight in each component such as pipe and silencer rather than just removing sound reducing materials.
• The appearance is also beautiful and provides a rear view with an aggressive impression.
• New series feature a titanium tail tip cover instead of carbon.
