MagnaFlow's stamped Y-Pipe transitions are ideal if you’re looking to design your exhaust for a single inlet, dual outlet set up. Made of stainless steel, MagnaFlow Y-Pipes offer a gentler radius that allows for better balance between cylinder banks and consistent flow in tight constrained areas. Available in several diameters and configurations including the regular Y, 90° inlet, and giant 4", our Y-Pipe transitions are also backed by a lifetime warranty.
