The WS Exhaust series is A'PEXI's 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 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.

Exactly what I was looking for!
At first I was looking for a comptech exhaust before i realized that exhaust is no longer being made...Just purchased this and put it on and I love the look and the sound...Not to loud which is exactly what i was going for and looks amazing.

Excellent, quiet but powerful exhaust
I brought this exhaust over more than a year ago and I love it. I have it installed on my stock Integra LS and it gave it a nice sound and little boost in performance. If you're looking for something loud, this isn't it. But this exhaust is just as good but quiet.

This is a great exhaust if you want a very subtle exhaust note with nice gains, and do not want to deal with the drone of a louder exhaust for daily driving. I fell into this category as the RSX is my daily driver, and I must say this is a beautiful exhaust... really looks good sitting behind the car, has just enough tone to where you can hear it at WOT but otherwise its a low overtone that is transparent while you cruise along. A'PEXi quality of course is second to none. My first impressions were that it was almost too quiet, however I've come to appreciate the high quality tone that it does provide under acceleration. I'm sure mods such as header, test pipe, intake, etc will bring out more tone from this exhaust. If you want something you can honestly hear well all the time, then this probaly isn't the right exhaust for you... if you want a sexy and subtle note to your RSX then this is the exhaust system is absolutely perfect.

this is the sh*t. I really liked how it sounds... it goes great with my header... but I was kinda dissapointed because it came with some missing screws =(... installation was a breeze tho

Perfect for everyday
have had this exhaust on for a week... perfect sound... carbon building inside pipes, gotten little deeper... deep idle, quiet when cruising, and can hear it (great tone) when at wot, aem v2 intake louder or about equal in db at wot. clean, quality sound that you notice only when you want. had straight through exhaust (will not name, but smaller muffler) that drove me crazy on road trips (the "drone"), actually more low to mid range torque in my opinion, about equal on high end. v2 intake, throttle body spacer, header, downpipe, WS2, quaife, exedy flywheel and clutch all from clubrsx, great service and prices fellas!

Very nice looking exhaust. Sound is barely louder than stock (you won't notice) unless you are at WOT and then it still isn't very loud. Perfect for a modest performance gain. Looks and fits great.

Bought this last year, Fits great. Nice deep sound, noticeably louder than stock when WOT, and comfortable quiet during daily driving
