Resonated test pipes effectively increase low end torque and maximize power throughout the entire RPM band. Built as a direct OEM replacement, resonated test pipes are designed to be an addition to your cat back exhaust system. We maximize performance by eliminating your OEM catalytic converters, increasing the tubing diameter, and adding straight through perforated core resonators to free up back pressure. This addition is ideal for force inducted applications because of its straight through design, eliminating virtually all restriction. These pipes replace your factory catalytic converters, letting all the exhaust pass through freely, but not the noise. Plain test pipes offer the highest level of flow, but often result in a "raspy" exhaust note between 3-4k rpm.

Installing aftermarket Test Pipes or Downpipes will not void your vehicle's entire warranty. If you’re in the United States, the Magnuson Moss Warranty Act ensures your warranty remains intact unless the modification is proven to directly cause a failure. The purchasers are entirely responsible for informing themselves of the applicable laws where the products are to be used and to comply with those law. The more power you can get out of your exhaust system, the better it flows.

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.
