STOCK COMPARISION
The exhaust flow design was the main focus in the pipe design, the best pipe thickness for weight and strength with pipe diameter to suit torque and all power gains throughout the entire power band.

 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 sub silencer was designed with a simple structure and minimal size to reduce unwanted noise. Without hindering exhaust gas flow.
Designed For True Performance Use.
 
・Lightweight (For total balance)
・Optimum Exhaust Flow (To extract the engines full potential,
Will benefit greatly with additonal tuning.)

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.

 3 PIECE ASSEMBLY
No flanges were fitted for increased weight savings and for a better finish with the race look secure springs and clamp methods.
 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.
 
 PERFORMANCE VALUE
The best performance is made possible with the best materials and still with keeping it within everyone's reach.
 HIGH SOUND QUALITY
Only the racing layout muffler design in full Titanium can produce the exhilarating race sound that is second to none.
