Tomei products have been utilized in nearly every motor sport imaginable. Tomei???s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei???s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei???s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency.

An aftermarket exhaust system is one of the most popular purchases for any car enthusiast looking to modify for their vehicle. This is because an aftermarket exhaust increases performance, sound, and is relatively easy to replace. An engine is basically an air pump, the faster you can flow more air through an engine the more power it will produce. A factory exhaust system was not made with peak performance in mind. Factory units are designed to reduce cost, decrease noise, and be easily mass produced, all of these objectives sacrifice performance. Because upgrading your exhaust allows your engine to breathe more freely throttle response is also improved along with horsepower and torque. Last but not least a less restrictive exhaust system will give your vehicle a more aggressive tone over stock.

It is commonly known that a turbocharged vehicles performance can be improved by reducing the secondary exhaust pressure after the turbine. That???s why Tomei has developed this downpipe and front pipe combination. Tomei has invested over a year in researching all possible aspects and combinations for the best performance gain throughout the entire RPM range. The end result was a decrease in exhaust resistance in all areas and best results is achieved with their downpipe and front pipe as a combined set. Tomei???s pipe diameter is 65mm, 10mm wider than the factory piece. The corrosion-resistant SUS304 stainless steel material used in manufacturing this product makes it more heat resistant as well as more lightweight.
