Flowmaster Scavenger X-pipes are able to provide gains in horsepower and torque without sacrificing the classic Flowmaster sound. These X-pipes feature Flowmaster's patented Scavenger D-port technology designed to create a larger surface area that actually pulls gasses along faster—delivering an increased torque curve throughout the rpm range. Scavengers are constructed from mandrel-bent stainless steel and are offered in different diameters to help you find the one that will complement the rest of your exhaust system. Performance gains for your car or truck begin with Flowmaster Scavenger X-pipes.
