The new Tomei Powered
product concept is to "Achieve performance gains with a lasting
impression". The new developments have been involved with a new type of
performance mufflers. In recent years more end users are enjoying their cars
with clubman sports events and also for more serious competitors entering their
cars in serious track events where various constraints have been with their
mufflers being restrictive, so we have designed our mufflers for pure
competition use for results when needed.
We wanted to design an exhaust system for absolute total engine performance.
The main priorities were for overall engine performance gains as opposed to
just maximum peak power. The tubes size and length was carefully selected to
suit each engine characteristics and to suit the cars chassis as well for
maximum torque, response, and exhaust flow efficiency through the layout. It is
difficult to increase the power on the EVO X with the muffler alone but this
design has optimized in all areas. The use of Titanium material with the single
piping layout also helped reduced the overall weight of 15.65kg! This amazing
weight reduction helps with the cars performance and handling whilst
maintaining strength that Titanium can deliver.

1. TAIL PIPE

Æ115 t=1mm design with straight cut finish racing model for
that Spartan look. The Titanium look with the laser marking and beautiful
heat gradation gives the EXPREME Ti a good visual appeal.

|
2. Silencer Band

Made from stainless steel the band this band is designed as a
support band instead of having is welded to the actual muffler. This keeps
both separated and greatly reduces stress from vibration that would usually
be present if the support was welded directly to the muffler. The band is
also fitted with a special high heatproof spacer rubber for increased stress
reduction from vibrations.

3. CLAMPS

Rather than the conventional T-type bolt the clamp band was
chosen as it provides double the clamping force even under harsh conditions.
This band is best suited for extreme conditions from high heat stress and
vibrations this will firmly keep the pipes air tightly sealed together.

4. Silencer

Silencer Case
All of the ¦152 t = 1mm Titanium design achieves the optimum
exhaust efficiency and straight design, finished off with a mirror finish
plate with the embossed logo and heat gradation color for that lasting
impression.
Punched Mesh
The all Titanium made inner mesh tube is t=1mm Æ3 P=5mm with
an open slot ratio of 32.6%. With maximum weight reduction and exhaust flow
being the key points you can expect the best flow rate with an addictive
racing sound from this exhaust without any compromise.
Glass Wool
Unlike the usual conventional short fiberglass threads, the
use of the long fiberglass thread wool was chosen for its excellent sound absorbing
and excellent durability to cope with high pressure and high temperatures

5. Precision Welding

Titanium is well known to be the most difficult to weld with for
best results as the pre-preparation is required to remove dust and grease
from the material. Once the optimum conditions are achieved then with the
right strictly controlled welding methods with the heat rate and speed will
then make it possible to achieve the high grade finish.

|
6. Joint Spring

The hook anchor points allows the springs to firmly hold the
pipes together which is sufficient as it is alone but the use of the clamp
bands adds that extra guarantee for a secure fitment for a reliable joint.
|
|
7. Main Pipe

The main purpose for this product is for pure competition
performance exhaust efficiency so the racing layout design was made with bare
minimum bends as possible over the entire ¦80mm t=1mm Titanium piping and the
3 piece for ease of installation and weight reduction.
|
|
7. Flange

The flange was made from a 6.0mm plate for strength design
purposes to minimize distortions and cracks from aging to guarantee strength.
This keeps the light weight design yet maintains strength equal to the
factory stock design and guarantees the sealing characteristics that is
required.

ORIGINAL TITANIUM
MATERIAL

STRENGTH
Titanium being pliant allows the thickness of the material to
be made thin yet it retains superior strength properties. Because of this,
further weight reductions were made possible.
DURABLE
Titanium is highly resistant to heat and corrosion so the
muffler can still remain stable even in extreme competition conditions.
LIGHTWEIGHT
Tomei Titanium Catback exhaust only weight approx. 10 lbs versus stock at
approx. 45 lbs.
