The WS II Exhaust series is the A'PEXi answer to the ultimate street muffler system with all around performance. The canister is made of the highest grade polished SUS304 stainless steel while the mandrel bent piping consists of high temperature, titanium particle coated mild steel. This muffler has always been the standard for aftermarket street exhaust systems. The oval canister houses a newly designed rolled tip for an extremely high class finish. Interior construction has been fine tuned for even more low to mid-range power. Countless magazine dyno tests have proven the WS exhaust to be one of the best all around exhaust systems on the market. As always, all A'PEXi cat-back exhaust systems come complete with all necessary hangers, nuts, bolts and gaskets.The World Sport II muffler is for the performance enthusiast who has more on their minds than just pure power. This system is designed to provide excellent low and mid range power without excessive noise.
