1991 Nissan 240SX Exhaust System at Tuners Depot

The N1 series muffler has become a staple of the import tuning industry. The N1 was the first of its kind to incorporate the classic angled muffler design that has became so familiar with today's street cars. Born from Apexi's involvement in the grueling N1 endurance series, the N1 exhaust system pairs a straight through design racing muffler with free flowing, mandrel bent piping (60.5mm N/A, 80mm for turbo applications). The combination has resulted in dyno proven horsepower and countless satisfied customers world wide. Designed with track use in mind, durability is of utmost importance. The polished SUS 304 stainless steel canister features robotic TIG welding for an immaculate finish and years of reliable performance. The mild steel piping is treated with our special high temperature titanium particle coating. The N1 is truly THE benchmark in which others strive to duplicate.

The N1 Evolution combines all the racing heritage and proven performance of the original N1 muffler but raises the ante by adding light weight, fully polished stainless steel piping. This is the ultimate N1 exhaust system. Mandrel bent, full stainless steel construction provides maximum power gains and resistance to rust or other damage caused by weathering. Like the original N1, the N1 Evolution uses the minimum amount of pipe bends to allow for greater exhaust flow. The N1 Evolution was created for those who are looking for something one step further than the classic N1 design. Available only for a select amount of vehicles, the N1 Evolution stands as a brilliant testament to exhaust system fabrication. * Please note that, due to the tapered tip of the N1 Evolution exhaust system the ATS Silencer WILL NOT fit properly. This is only true for the N1 EVOLUTION mufflers, all other exhaust systems will fit without problems.

The NOIR (nw?r) muffler was developed specifically with the diehard street car enthusiast in mind. Over the years it has became increasingly difficult to street drive a modified "sport compact" in some parts of the country. Staying low profile is an important issue to many street tuners who don't want to deal with the negative stigma sometimes associated with modified imports. The NOIR Muffler is designed to be quieter than a typical racing exhaust while its stealthy black coating minimizes your chances of generating attention from unwanted sources. The WS style canister and 100mm tip finish off the system with a classic sporty look without being over the top.

The N1 Dual is a hybrid variation of the N1 exhaust. This system incorporates a twin pipe, twin canister design for improved mid-range torque without sacrificing top end power. The twin piping is constructed of mild steel with a titanium particle coating mated to SUS 304 polished stainless steel canisters. Each canister features a polished 90mm (3.54 inch) tip. Robotic TIG welds compliment the hand crafted MIG welds to create on of the most innovative and dynamic exhaust systems on the market

The GT Spec Muffler is the ultimate in high power exhaust systems. Previously available only for select GT class vehicles, A'PEX proudly offers the GT Muffler for a wide variety of popular vehicles. The GT System is a FULLY polished stainless steel exhaust utilizing a massive piping diameter channeled through a 114.3mm (4.5 inch) tip. A'PEX proudly stands as one of the only manufacturers in Japan to own and operate a 95mm mandrel pipe bender. An A'PEX Silencer is included to suppress exhaust sound output for street applications. By using even lighter SUS 304 stainless steel piping to save weight, the GT Series muffler stands as the benchmark of power, craftsmanship, and design. Each muffler incorporates immaculate robotic TIG welds as well as hand crafted welding.

The N1 ExTi (Expert Titanium) offers all the performance and quality of our race proven N1 Exhaust systems plus the incorporation of an ultra light weight titanium muffler section. For years, the N1 Titan has only been available to our customers in Japan; A'PEX USA is pleased to be able to offer this muffler to the US tuning market under the N1 ExTi name. The N1 ExTi utilizes full stainless steel piping mated to an immaculately constructed Titanium N1 Muffler. The muffler section features a full titanium canister which discharges through an adjustable length 115mm super heated (burnt) titanium tip. The 5 step adjustment range of the finisher tip is designed to allow users with aero kits the ability to extend or retract the tip to meet the dimensions of the rear bumper.
