The Ultimate Exhaust - Form and Function
CHARACTERISTICS
High-end power, includes silencer
COMMENTS
A'PEX GT Spec Mufflers are A'PEX's flagship line of exhaust systems. These race-bred exhaust systems were engineered to handle extremely high-horsepower applications. A'PEX is the only company in Japan to own and operate a 95mm (3.74 inch) mandrel pipe bender at this time. A'PEX proudly incorporate this 95mm piping on select applications to offer exhaust systems unmatched by any other manufacturer. Pipes for the A'PEX GT Series are designed with minimal amount of bends and the canisters project at an angle like the A'PEX N-1. The A'PEX GT Series pipes and canisters are constructed of polished SUS 304 stainless steel. The 115mm polished tip give the A'PEX GT Spec Mufflers an aggressive, yet refined style. All A'PEX GT Spec Mufflers include the A'PEX Super Silencer, which can reduce noise levels by up to 7 decibels.

A'PEX WORLD SPORT SERIES II MUFFLER
CONCEPT
Ultimate street muffler system with all around performance
CHARACTERISTICS
Mid to high-end power
COMMENTS
The canister is made of the highest grade polished SUS304 stainless steel with titanium particle paint coated mild steel piping. This muffler has always been the standard for aftermarket exhaust. The oval canister houses a newly designed fully rolled tip for an extremely high class finish. As usual, all A´PEX cat back exhaust systems come complete with all necessary hangers, nuts, bolts, and gaskets.
APEX quality welding and material set the new WS II Exhaust apart from cheap imitators. 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. Multiple vehicle applications also add to the WS Exhaust success.
All WS II exhaust systems comply to emission laws because they do not modify or relocate the catalytic converter and factory O2 sensors. Since the legality of exhaust products is based on them being considered "direct replacement" parts there is no certificate necessary to issue for this series. For "add on" or "modified" parts which require an Executive Order (EO) number there is a mandate for an under hood label which must be included with the product. The WS Series is "functionally identical" to the OEM part it replaces during the condition under which emission testing is conducted. Sound levels of the WS series also average in the mid to high 80dB range.

A'PEX N-1 SERIES MUFFLER
CONCEPT
Minimal number of bends for maximum efficiency
CHARACTERISTICS
High-end power
COMMENTS
In the N-1 Endurance Race, efficiency is everything. With that in mind, the A'PEX N-1 exhaust systems were born to satisfy the want for quick throttle response and to effectively handle the rigorous demands o high-horsepower engines. The pipes were engineered with the aid of sophisticated CAD systems to develop the straightest possible lines and least number of bends. The straight-through canister projects from the car at an angle, which helps smooth the exhaust flow. The canister is built from SUS 304 stainless steel and features a 115mm tip with aggressive style. The A'PEX Super Silencer is included on selected models, which can reduce noise levels by up to 7 decibels. The A'PEX N-1 Series Mufflers are available for both NA (naturally aspirated) and turbo-charged cars.

A'PEX N1 DUAL MUFFLER
CONCEPT
Retain the same peak HP of the single N-1 while improving mid range torque
CHARACTERISTICS
Mid to high-end power
COMMENTS
A'PEX N-1 Dual Mufflers are a variant of the popular single-tip N-1 Series Mufflers. The A'PEX N-1 Dual piping splits into two smaller diameter pipes just after the catalytic converter and flow into a pair of 120mmcanisters. The canisters are polished off with aggressive 90mm tips. The use of smaller piping diameter helps retain more mid-range torque. The A'PEX Dual N-1 does not sacrifice peak horsepower because the dual pipes can handle more exhaust gas volume. Piping is treated with high-temperature titanium particle coating, and the canisters and tips are constructed of polished SUS 304 stainless steel. Optional 90mm A'PEX Super Silencers can be used to reduce noise levels by up to 7 decibels.

A'PEX Noir MUFFLER
CONCEPT
The NOIR Muffler is based on the original "World Sport Muffler" Canister and Tip.
CHARACTERISTICS
Mid to high-end power
COMMENTS
The Apexi NOIR (nwär) Muffler was developed specifically with the diehard street car enthusiast in mind. The NOIR Muffler is designed to be quieter than a typical racing exhaust while minimizing chances of unwanted attention with its stealthy black coating. It has become increasingly difficult to drive a modified “sport compact” on the streets. Staying low profile is an important issue to many street tuners that wish to stay clear of negative stigma sometimes associated with modified imports. The WS (World Sport) style canister with a 100mm tip finish off the system with a classic sporty look without being over the top.

COMMENTS
Designed for hard tuned, street driven vehicles, the PS Revolution's exhaust pressure activated "active valve" system provides the hardcore enthusiast with the best of both worlds. The retracting valve is engaged and disengaged based upon exhaust gas pressure. This revolutionary new muffler design allows high powered street cars to maintain a tolerable, and legal, exhaust note at idle and light throttle acceleration while completely disengaging during high throttle, high load situations. Never before has an exhaust system seamlessly fused the streetability of a stock exhaust system and the performance of a low restriction racing exhaust. Like all A'PEX exhaust systems, the PS Revolution features a high quality SUS 304 stainless steel muffler. Being the standard for performance and reliability, the PS Revolution uses full stainless steel mandrel bent piping for added strength and minimum weight.

COMMENTS
A'PEX Universal Series Mufflers can be used in the fabrication of practically any exhaust system. The muffler consists of a canister and tip, which must be welded onto custom piping. Sound levels must be controlled through piping diameter and the effective use of resonators. Please consult your local tuner or muffler shop for advice on sound level tuning. A'PEX Super Silencers, capable of lowing noise levels up to 7 dB, are also available for purchase for 90mm and 115mm tip canisters. The A'PEX Universal Series Mufflers are available in the popular Dunk and N-1 models. The N-1 models are available in a variety of colors.
