TOMEI Full Titanium EXPREME-Ti Exhaust System (for USDM Bumper) for CT9A Mitsubishi Lancer Evolution VIII / IX

TOMEI’s product concept is “To produce a great product for ultimate driving pleasure”. Their latest product developments focus on new Titanium exhaust systems. In recent years, a growing trend in clubman racing series has seen more users enjoying their cars at track events. Recognizing the power restrictions of currently available bolt-on exhaust systems, TOMEI decided to create a superior product, not just for power but also for weight reduction and best value for money.

RACING LAYOUT

• TOMEI focused on minimal bends and curves in the design of this product to achieve the best exhaust efficiency, resulting in supreme performance.

3 PIECE ASSEMBLY

• TOMEI opted not to fit flanges, prioritizing increased weight savings and a better finish.

PERFORMANCE VALUE

• The best performance is achieved using top-quality materials, while still being kept within everyone’s reach.

DRY RACE SOUND

• TOMEI’s Titanium material exhaust produces the instinctive sound of a true race exhaust, delivering an intoxicating dry race exhaust sound.

Design

• TOMEI aimed to design an exhaust system that enhances the driving experience by improving the engine’s sound. The main targets were increased performance gains, optimal power, and response. By utilizing minimal bends and the optimum pipe size, they achieved this goal. Improving engine performance with just the muffler system alone is challenging. Therefore, using their Titanium material, TOMEI further reduced unwanted weight without compromising the product’s overall strength. With a strong commitment to their values and targets, they created a product for all to enjoy.
• TOMEI developed their product based on the philosophy of enjoyment and results. Their Titanium material, created with revolutionary methods, helps save on unnecessary costs, allowing them to pass the savings to the customer. This high-quality product is offered at an unbeatable price. The package includes everything needed to install the product straight out of the box, with all springs, clamps, bands, and bolts included for immediate installation. TOMEI has done the hard work, so customers can enjoy their cars with confidence in the product’s lasting quality.

Original Titanium Material: Lightweight – Strong – Durable

• TOMEI sources its own raw materials, significantly improving quality while maintaining low prices. Complete control over the raw materials and manufacturing process allows Tomei to produce high-quality products at affordable prices.

Tailpipe

• TOMEI’s products are made from Titanium material with a 115mm diameter and 1mm thick piping. Designed with a straight cut and finished for race use, each piece features the EXPREME Ti logo laser-etched on the tip with a Titanium gradation blue color.

Clamp Band

• TOMEI’s clamp design is much stronger than the conventional flange and bolt type. It securely holds the pipe in place, maintaining an airtight seal while withstanding high heat, stress loads, and vibrations.

Silencer Case

• This component is made from Titanium with a pipe size of 152mm and a 1mm thickness. The oversized shell design optimizes exhaust gas flow, aiding in power gains. The embossed TOMEI logo and heat gradation coloring provide a distinctive finishing touch.

Punched Mesh

• Crafted entirely from Titanium with a 1mm thickness and an open slot ratio of 32.6%, TOMEI’s high flow design delivers a distinctive racing exhaust sound, combining lightweight Titanium material and optimal flow dynamics.

Glass Wool

• TOMEI uses long fiber wool threads for the silencer, proven to last longer than traditional fiberglass materials. This design endures high temperatures and pressures over extended periods.

Connecting Springs

• TOMEI’s pipes are connected using a hook and spring design, allowing slight movement to absorb vibrations. While the hook springs alone are sufficient to hold the pipes together, the best results are achieved when using both the clamp band and springs.

Precision Welds

• Titanium is challenging to weld, but TOMEI’s experienced methods ensure superior strength, durability, and finish quality. Utilizing the right equipment and meticulous attention to detail, TOMEI achieves the high standards expected from their products.
