You ever notice know how when car people talk about their engines, and then one of them mentions headers, the next question seems to always be, "Are they Tri-Y headers?" You can blame Doug Thorley Headers for that one. Not only did the company invent the Tri-Y header design way back in 1958, which allows spent gasses to escape much more efficiently, it has also been designing and manufacturing many other exhaust components for more than 50 years! Another reason to look into Doug Thorley Headers: they are still made in the U.S.A. Oh, and did we mention that every header that Doug Thorley Headers produces is C.A.R.B.-approved? Californians rejoice!
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: 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 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.
