The Vortex ® Insert Cone is an excellent way to reduce the noise level of your exhaust without robbing a lot of power. Installed near the exit of the exhaust, it provides a large friction area to reflect and dissipate sound energy. Unlike most mufflers, the open area of the cone is actually greater than the area of the collector or exhaust pipe, thus reducing backpressure. Ultra lightweight (1/2 lb.), 100% T304 Stainless and easy bolt in installation. Available in 3.00, 3.50, 4.00 and 4.50 sizes. Designed to fit inside any of the listed tube sizes.
