Apex Integration (A'PEXi) Exhaust System, WS2 Muffler (Dual L/R), 04- TSX, 60mm 116-KH30

The WS Exhaust series is the A'PEX 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'PEX cat back exhaust systems come complete with all necessary hangers, nuts, bolts, and gaskets.

The World Sport 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. The sporty, yet elegant look is made possible by using a polished SUS 304 stainless steel muffler, 60mm titanium particle powder coated mild steel piping, paired with a 100mm (3.93 inch) polished tip. Robotic TIG welds along with precise hand crafted welds ensure maximum longevity and performance. The WS system possesses all of the motorsports passion and intensity associated with A'PEXi products. This system is ideal for the daily driver car of an enthusiast, or for vehicles that want the high class sporty look without the noise.

A'pexi is one of the most underrated companies in existence. It was started by former employees of HKS about 20 years ago. Those of you older than 25-30 years may recall HKS as being the grand old godfather of our import performance industry. The tuning firm has focused on quality from day one and you can see it in their products. Even Apexi packaging is head and shoulders above the competition. The names HKS, Greddy, and Apexi mean less today than they used to. But remember that they all come from Japan and embrace the same principles that less conventional companies hold true!

The N1 is their big power system. Apexi has dominated the power exhaust market in the past with the N1, and practically invented the angled canister look.

However the noise and ground clearance compromise has little place on the street as law enforcement grew more and more strict with exhaust mods. Noticing the street success of the Greddy SP2 Apexi released the World Sport exhaust as part of the WS lineup that included specially tuned suspension kits which were all designed for reliable street use. Since then the WS has been a great alternative to the trademark large canister style of the SP2.

Over time, the WS has eveloved to meet market demands and 5-6 years ago the WS exhaust became the WS2, with a new slash cut style tip. But the large canister muffler style stayed, as did the near perfect exhaust note. You need to remember, the WS was invented at a time when the cops were on the hunt for rice rockets in force. So anything exceeding CA legal decibel limits was at risk of causing issues. So the WS was designed to meet the decibel limits of OEM manufacturers. Meaning the WS2 is about as aggressive as the most aggressive stock exhaust in terms of sound. It is tuned to be heard but not annoying. It does not drone at all. It enhances the nature of a sports sedan in a perfect way: without ruining the car!!!!

Power gains are moderate with this system. Larger mandrel bent piping and high flow mufflers will enhance the performance. The goal of this muffler is to make the car more fun on the street meaning a little power, a little sound, and a great look!

OH! And it should be noted that APEXi developed and tuned this exhaust on an employee car. Extensive R&D went into it to get the sound and fit right!
