This is the second version of the Hi-Power Spec L series muffler. A renewal that allows for the muffler tip finisher cover to be exchanged in between different materials and style for the ultimate choice in the finishing touch. A pure sports spec series muffler designed with the ideal combination of hi-power and ultra lightweight spec. It produces a high quality sports sound with Advantex wool-equipped silencers while maintaining street legal JASMA status. Significant weight reduction between 30~60% has been achieved with ultra efficient compact silencers, construction and materials. A weight close to many titanium mufflers while maintaining the more cost-effective price of high quality stainless steel.
