The Tomei product concept is "To produce a great product for ultimate driving pleasure". This time our latest product developments have been in these new Titanium exhaust systems. In recent years we have seen a growing trend in clubman racing series and more users enjoying their cars at track events. Seeing that there are power restrictions from the bolt on exhaust systems that are currently available on the market, we have decided to make a better product. Not for just power but for weight reductions and the best value for money product. So here we have our true competition use design exhaust system.

We wanted to make an exhaust system that will allow you enjoy your car more from the sound of the engine. Increased performance gains with the best power and response was the main target points. Through the use of minimal bends and the optimum pipe size we were able to achieve this goal. To improve the performance of the engine with just the muffler system alone isn't easy. So with the use of our Titanium material we were able to further reduce unwanted weight without compromise to the products overall strength. So with the strong commitment to our values and targets we were able to make a great product for all to enjoy.

Our product was developed based on this philosophy, for enjoyment and results. Our Titanium material was developed with new revolutionary methods which helps save on unnecessary costs which help us pass the savings on to you. A high quality product at an unbeatable price. The package includes everything that is needed to install the product straight out of the box. No need to hunt for any additional parts as all the springs, clamps, bands and bolts are included to get this product onto your car immediately. We've done the hard work for you so you can enjoy your car with our product and know that the quality is there to last.



High quality production, for true competition use without compromise. Only the best Titanium grade materials are used. From the special racing layout design, made as straight as possible, to the high flow silencer. We have poured our knowledge into it all. When you see our EXPREME Ti system, you can then understand that ours is unrivaled.


In order to achieve the best performance possible from this product. We have designed the layout of this exhaust system to be as straight as possible. By minimising bends and the angle of the bends, we were able to maximise the exhaust gas flow efficiency.


The conventional style flange is not used to help reduce weight even further. The use of the springs and clamps eliminates the need for gaskets as well.


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.


Only the racing layout muffler design in full Titanium can produce the exhilarating race sound that is second to none.


The design targets were strictly for performance use and for the best value for money for our end users.
