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.


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


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


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


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


  • 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.


  • 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.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at with any inquiries.
