Tomei SUS304 Test Pipes Nissan 350Z VQ35DE 03-06

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. 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. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

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.

From the factory exhaust pipes are fitted with catalytic converters, which are basically mesh screens that heat up and burn unused fuel. This is extremely detrimental to exhaust flow, thus hurting performance. Tomei test pipes are designed from SUS304 grade stainless steel to resist corrosion. Their strait through design means you will have an increase in horsepower and torque throughout the entire RPM range as well as increased throttle response. The pipes are 60mm in diameter helping to flow more air than stock. By eliminating the 4 factory catalyst cells Tomei was able to make a more efficient, lightweight exhaust pipe. Tomei’s test pipes weigh only 4kg opposed to the 12kg factory pipes.
