 RACING LAYOUT

When aiming for true performance efficiency, we had chosen to design the exhaust with the least amount of bends as possible. Just like the true purpose built race cars, in a racing layout design, yet to still comply with the stock body design so it can be fitted to any street used vehicles.

 
 TOMEI
 
A : MAIN SILENCER/ TAIL END
Compared with the stock design, our design is single piping all the way for max weight reduction. We have also focused on the design of the muffler to produce the best exhaust sound without compromising performance.
B : MAIN PIPE
The pipe diameter was chosen for optimum exhaust flow efficiency. For performance use in mind and weigh reduction. Thus the slide joints was made instead of using the conventional flange and gasket design.
C : SUB SILENCER
This design was adopted for maximum exhaust flow efficiency without comprimising the quality of the structure and sound.
○
Designed For True Performance Use.
 
・Lightweight (For total balance)
・Optimum Exhaust Flow (To extract the engines full potential, Will benefit greatly with additonal tuning.)
 
 STOCK MUFFLER
 
D : MAIN SILENCER
This is even larger than the mid section, to help reduce noise, smog & exhaust emissions. All to comply with street use regulations. The internals are complex and very heavy which greatly hinders performance.
E : MAIN PIPE
Torque quality and sound are restricted. The piping layout is designed mainly to help reduce thermal damage to the surrounding parts.
F : SUB SILENCER
A pre-muffler setup that helps reduces exhaust noise. This further assists the purpose of the main muffler.
×
Inadequate For Real Performance Use.
 
・Heavy　・Poor Exhaust Efficiency
 
 
 
 3 SECTION PIPE ASSEMBLY
The conventional style flange is not used to help reduce weight even further. The use of the springs and clamps eliminates the need for gaskets as well.
 HIGH DURABLE GLASS WOOL

The long fiber wool threads were adopted for the silencer. This type has proven to last longer than the traditional fiberglass materials even over a longer period of time with extensive high temperature exposure both at high and low pressures.
 
 BEST VALUE & PERFORMANCE
The design targets were strictly for performance use and for the best value for money for our end users.
 HIGH SOUND QUALITY

Only the racing layout muffler design in full Titanium can produce the exhilarating race sound that is second to none.
