Concept:
Aggressive tip size with modern canister design
Characteristics: Mid to High end Power
Comments: The Original trend setting DUNK inspired earlier versions of
the ID (international DUNK) and countless "knockoff copies." The canister and
tip are both constructed of a polished SUS 304 stainless steel and the piping is treated
in a titanium particle based high temperature paint to prevent high temperature cracking.
Despite the 130mm tip, the exhaust actually looks smaller from the rear view due to the
rounded 200mm canister. This allows you to hide the full potential of your vehicle
performance. The high level of finish, 130mm tip size, and real HP increase all keep the
DUNK one step ahead.
Available for:
- 240SX '89-'98
- 300ZX '90-'96
- Supra '86-'95
- Celica '90-'94
- RX-7 '86-'95

Concept:
Intimidating looks, and dyno proven HP gains
Characteristics: mid to high end power
Comments: The DUNK 115 Series was designed especially for U.S. spec
vehicles that differed from their Japanese counterparts ion engine design and catalytic
converter placement. The DUNK 115 Series are all made to U.S. market demands with full
60mm piping and a straight through canister design. The 200mm SUS 304 Stainless Steel
canister also allows for ample ground clearance. The tip is also constructed of a polished
GUS 304 stainless steel. Piping is treated in a high temperature titanium particle based
paint. All of the DUNK 115's have a 115mm-tip size, which allows the user to use our SUPER

| N1 SERIES |
 |
Concept: Minimal
amount of bends as possible for maximum efficiency
Characteristics: High End Power
Comments: The angled muffler. A'PEX was the first to produce this type of
muffler style on a manufacturing basis in Japan. A'PEX has continued to pioneer new and
more efficient ways of making exhaust systems from day 1. Engineered from feedback data of
our N-1 series racecar, the N-1 stands as the SECOND benchmark exhaust system from A'PEX.
In an N-1 Endurance Race, efficiency is everything. That is why all of the N-1 exhaust
pipes aim for the straightest possible line with the least number of pipe bends. This
allows exhaust gases to pass smoothly through the piping. The exhaust system canister is
made of a rugged SUS 304 Stainless steel and features a 115-mm tail. The canister projects
from the car at an angle, which also contributes to smooth flowing exhaust. Because all of
the exhausts are straight through design, throttle response and horsepower levels are
improved. The N-1 Series Exhaust is available for both NA (Normally aspirated) and
Turbo-charged vehicles.
Available for:
- 240SX '89-'98
- 300ZX '90-'96
- Supra '86-'95
- Celica '90-'94
- RX-7 '86-'95
- Miata '90-'93

DUAL |
 |
Concept:
Retain
the same peak HP of the single N- I while improving mid range torque
Characteristics: Mid to High End Power
Comments: The N-1 Dual is a variant of the smash hit N-1 single. The Dual
N-1 splits into two small diameter pipes that flow into two 120mm canisters with two 90mm
tips at the end. The Dual pipe configuration starts right after the catalytic converter
with computer aided pipe bends and clearance adjustments. The Dual N- I achieves greater
power than the single N-1 because federal regulations prevent the single N-1 piping
diameter from being excessively big. This means that the dual pipe design of the Dual N-1
flows more volume of exhaust than a single pipe could while retaining more mid range
torque at same peak HP. As with the single N-1, the Dual N-1 canisters and tip are
constructed of a SUS 304 polished stainless steel while piping Is treated to a titanium
particle based high temperature paint.
Available for:
- 240SX '89-'98
- RX-7 '86-'95

and canister. The GT series incorporates 95mm piping (3.74 inches) for maximum power (some
vehicles.) A'PEX is the only company In Japan to own and operate a 95mm mandrel pipe
bender at this time of press. Piping for the GT series minimizes the degree of bends.
Canisters project at an angle like the N-1.

INTAKE |
 |
Concept: Air
filter with least amount of turbulence
Characteristics: Dual stainless steel funnels to direct intake air
smoothly into the throttle body
Comments: The A'PEX Super intake is the premier air filter system using a
dual funnel technology. The air filter is made of an unrestricted race quality element and
has one funnel at the top of the filter and one funnel at the base.
A'PEX engineers noticed in tests that when the vehicle sucked in air from the side, an
area of wind turbulence occurs in the middle of the filter. To cure this problem, a funnel
at the top of the filter was added to channel the air down to the base of the filter. A
separate funnel at the base of the filter ensured the smooth transition of air form the
atmosphere into the intake pipe.
Both funnels are constructed of a high quality polished SUS 304 stainless steel and the
craftsmanship only found in A'PEX products.
Available for:
- Universal (filter only)
- RX-7 '86-'95
- Supra '86-92
- MR-2 '91-'95
- Eclipse '95-'98
- 240SX '95-'98

| HYBRID
INTERCOOLER |
 |
Concept: To
create the ultimate front mount intercooler with exceptional cooling capabilities
Characteristics: Unique delta fin face, ultra low-pressure drop
Comments: The Hybrid Inter-cooler Series uses an exclusive cross flow
design on all the cores. These cores are the only cores designed specifically for front
mounting. The front of the core uses a delta fin typeface with two different types of
fins. The fins at the base of the delta wedge are tightly packed while the fins at the top
of the delta wedge are loosely packed. This allows the channeled airflow at the base of
the delta wedge to cool more air while the loosely packed fins on top prevent any
unnecessary wind turbulence.
Because of it's purpose built front mount design, all the fins are extended to the same
length at the rear of the intercooler. This allows the air to pass through without causing
wind turbulence in the rear of the intercooler and cool the remaining radiator and engine.
The GT Series incorporates the same technology but adds a new dimension of performance
with its thicker core sizes. TOP |
| TWIN
CHAMBER BLOW OFF VALVE |
 |
Concept:
Adjustable
sound, quick response, and fashionable blow off valve
Characteristics: Two-chambered body using an assisting vacuum hose
Comments: The APEX Twin Chamber Blow Off Valve incorporates a
revolutionary design in boost pressure release systems. Blow Off valves allows built up
boost pressures to escape into the atmosphere when the engine is no longer under load.
This prevents the pressure from backing up into the turbine compressor housing, causing it
to rapidly stop, and causing potentially destructive damage to the turbo. The blow off
valve is also adjustable to allow desired amounts of boost response between shifts. Unlike
conventional single chambered blow off valves, the Twin Chamber Blow Off Valve uses two
separate chambers with an assisting pressure hose. This design allows for a short and
highly sensitive spring in the first chamber that controls a piston and a valve in the
secondary chamber. The result, quicker valve response under low AND high boost pressures.
The blow off valve also gives the user the ability to adjust the blow off sound. By
turning a disk near the base of the unit, the exhaust gas release volume can be adjusted
to normal, loud, and extra loud.
Available for:
- Universal Fitment
- RX-7 '86-'96
- Supra '93-'98
- 300ZX '90-'96
- MR-2 '91-'96
- 3000GT '91-'95 (5 spd.)
- Eclipse '95-'98
