My test pipes where a great addition to my z and so far no check engine light. The fact that it is unlawful in many places in addition to your car being a respiratory danger is another reason why you should avoid replacing your catalytic converter with a straight pipe. Resonated test pipes are identical to standard test pipes, with the exception that a Helmholtz resonator is fastened to them. With less drone than non-resonated test pipes, they flow better than the stock cat-con and high-flow cats. Catalytic convertors are also necessary due to internal combustion engines’ ridiculously low efficiency. All of the hydrogen and carbon in gasoline would entirely burn out and transform into carbon dioxide and water in an ideal, frictionless engine.

A "quality" exhaust system maximizes performance gains by design. Both Test 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.

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!

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.

There are SO many of them on the road, and it’s a Model S, it’ll have vanity plates. Anyway, why don’t ya start clicking and see which cars your fellow Jalops think are only driven by idiots? Your MBRP product is backed with an industry-leading warranty. If any component(s) of your system does not meet our warranty standards,you're covered.

Items should be thoroughly inspected at time of delivery. Any damage NEEDS to be notated on the Bill of Lading prior to the driver leaving for an insurance to be valid. If damage, is not noted, the insurance is voided out and will need to be dealt with between you and the shipping carrier. You might have modified your car so that it runs at a higher boost pressure. If you have increased the amount of boost from a stock turbo system, then the increased exhaust output might demand a smooth, larger downpipe.

Talk to any engineer and he or she will tell you that getting air in and out of an engine is always a big problem. Promotions and discounts are unavailable on this item. This product will be sold by and is therefore only available for delivery to addresses within .

If you’re looking for unbridled horsepower, modifying your standard exhaust system might be a good option. A test pipe is just a straight pipe that replaces your catalytic converter. Could it be said g37 test pipes that the same type of idiot that liked the G35/37 coupe also went for the Hyundai Genesis Coupe? Our high flow catalytic converters will show almost equal gains, but straight throughs are a MUST for any FI application.
