Summit Racing™ Turbo Mufflers
Made with free-flowing large diameter tubing—as much as 20 percent more than some competitors—Summit Racing™ Turbo mufflers offer you deep performance tone without being too loud. They feature 2.5 in. internal cores with 360 degree perforations, roll-seamed end caps, 100 percent aluminized construction, and seam locked cores that prevent the center baffles from twisting out. Installation is a breeze with their fully reversible design. The mufflers are available in a variety of inlet/outlet diameters and locations. Order the model that best fits your application.
