The catalytic converter is the most limiting part of your exhaust system, as you undoubtedly already know. Although a test pipe is not something we advise doing, especially for daily driving, you can think about it if you want to get the most out of your exhaust system. Well, when you’re fitting a straight pipe in place of the cat, you’re messing with the burn ratio. When you fit a test pipe, you lower the pressure in your exhaust, and this fools the engine into thinking that it needs to work harder to maintain that pressure. One solution is to keep the original cat with you at your house.

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. 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.

Their commitment to excellence is reflected in every part they produce, making them a trusted name among car enthusiasts and professionals alike. Because of these reasons, Invidia front pipes and cat pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque. I am using these with my stock Nismo (g37 test pipes pipe/cat back) system. Gave the car some room to breath and still sounds stock ( no trumpets).

There are many other technical aspects such as "scavenging effect" which are beyond the scope of this document, but the point is, it's not as simple as just strap on a drain pipe and gains for days. A "quality" exhaust system maximizes performance gains by design. Normal downpipes have a catalytic converter that cleans the exhaust gases as they are produced. But these catalytic converters cause you to lose power as it has a restrictive aspect of cleaning the exhaust gases. The aftermarket performance part replacement for the catalytic converter for Nissan and Infiniti cars. YPerfomance’s auto engineers designed, developed, and tested this custom test pipe for the past years and got the best result for the perfect performance for Nissan and Infinity cars.

More air out simply means more air in, and this is what test pipes achieve.
