Tomei Expreme Ti Exhaust - Mitsubishi EVO X 2008+

Description

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.

Tomei 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 ar as. 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.



STRUCTURAL ANALYSIS
1. TAIL PIPE:
Tip diameter 115mm 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. CLAMP PIPE:
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 - 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 ö3 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 Ö80mm t=1mm Titanium piping and the 3 piece for ease of installation and weight reduction.

8. 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.
