Description:
APR Performance's cat-back exhaust for the 992.1 Porsche 911 Turbo and Turbo S 3.7L is built from T304 stainless steel with mandrel bends, TIG welding, and quad exits. The non-valved paths flow 66% more than stock and the valved paths 19% more, while the whole system weighs 37% less than the Porsche Sport Exhaust. Valves open at wide-open throttle for maximum velocity and close at cruise for a composed idle note.

Q: Does a cat-back exhaust come with a catalytic converter?
A: No, "cat-back" actually means from the rear of the catalytic converter back, so it will include everything after the converter, but not the converter itself.
Q: How do you install an exhaust system?
A: Exhaust systems are installed using the supplied hardware, which includes gaskets and high grade bolts. This is truly a bolt-on procedure and most exhaust systems are an exact fit with no modifications needed. For this reason, getting a performance exhaust system is normally considered one of the easiest ways to gain noticeable horsepower for your car.
Q: What exactly does "cat-back" mean when people say "cat-back exhaust"?
A: Many performance exhaust systems are also referred to as cat-back exhausts. Cat-back means that the exhaust piping starts from your catalytic converter and runs back all the way to the exhaust tip(s).
Q: What does an ehaust system do? Why buy an exhaust system?
A: A performance exhaust system is used to increase horsepower for your car by allowing exhaust gases to pass through your exhaust system with less backpressure and less resistance. Larger-diameter piping is normally used, depending on the application, in order to gain more horsepower and torque levels throughout the power band. A performance exhaust system can be the most cost-effective modification you can do to get more horsepower out of your car, not to mention that it will give your car a deeper more aggressive sound. And depending on the brand, performance exhaust systems normally include gorgeous new mufflers that add a great appearance to your car.
