The Vortex Insert Cone installed in a Turndown is an excellent way to reduce the noise level of your exhaust without robbing a lot of power. Installed at 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 exhaust pipe, thus reducing backpressure. The cone is 100% T304 Stainless and installed in a mild steel turndown. Available in 3.00, 3.50 and 4.00 sizes.
