SPDZ1 Nissan 350Z 370Z Infiniti G35 G37 Resonated Catless Downpipe Test Pipe Speedzone Performance LLC

A “quality” exhaust system maximizes performance gains by design. Both g37 test pipes Pipes and Downpipes, like the FLASHARK G37 Test Pipes and 370Z Downpipe, are designed to increase horsepower. By improving exhaust flow and reducing restrictions, they can add 10 to 20 horsepower on average, with noticeable gains during high-performance driving. Test Pipes are primarily used in place of catalytic converters and are designed to completely eliminate catalytic converters to reduce exhaust drag and increase power output, typically used in track and high performance applications. What an exhaust sounds like is typically the number one factor when choosing a system.

They use all factory mounting points and there is no modification to the vehicle. These will work with either aftermarket headers, factory headers, aftermarket exhaust, or factory exhaust. The Fast Intentions VQHR FI Resonated Test Pipes are the perfect upgrade for Nissan 350Z and 370Z owners with the VQHR engine. These test pipes are expertly designed to improve exhaust flow, delivering more power while maintaining a refined and balanced exhaust note.

Regulatory bodies are set up everywhere that monitors emissions from exhausts for this exact reason. This also acts as a check and balance for the throttle and fuel system, and if the sensor picks up different O2 concentrations than what’s normal, a check engine light will most likely appear on the dash. If a lot of oxygen is present, little fuel is being injected, and the O2 sensor sends a signal to the ECU to correct this. If there is little to no oxygen present in the burn mixture, the sensor sends a different signal to the ECU, which opens the throttle body more to allow more air to flow inside the engine. Keep in mind that engines are spinning at thousands of RPMs. Exhaust gases are being produced at the same rate, and for this, engines need a good exhaust route as much as they need fuel and air.

This gives an equal amount of flow, but with less raspiness. The exhaust note will only be slightly louder, and have a slightly deeper tone.Catalytic converters are the biggest “choke” point in the exhaust. These pipes have shown a 5-10hp increase at the wheels on factory 350z’s. Defective, damaged, or incorrect products We all know that accidents happen sometimes. If your product(s) arrive defective, damaged, or simply incorrect, please contact our customer service department as soon as possible. Please do not attempt to use, install, modify, or repair the part!

The resonated test pipes are constructed using high quality stainless steel. These resonated test pipes utilize stock flange locations so they can be used with stock components or aftermarket (Provided they aftermarket components use stock style flanges and mounting locations). To withstand the high temperatures laser cut cast steel flanges are used to ensure long lasting leak free reliability. This is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes required. Factory O2 sensor locations are also retained where required to ensure compatibility with factory systems.

A good example is Koenigsegg, which uses high-flowing cats in the exhaust system in every car they manufacture. Every car must come equipped with a catalytic converter by law, and depending on where you reside, it may be quite unlawful to remove this part from your exhaust system. Currently, only 50% of the thermal energy produced by an engine when a gallon of gasoline is used is transformed into mechanical force. If 50% sounds inadequate, keep in mind that the majority of cars on the road, especially the older ones, expel over 80% of their thermal energy through the exhaust.
