Vibrant Performance has created the TPV Mufflers to up hold the "Aggressiveness" of today's highly tuned high performance vehicles. The Mufflers feature Vibrant's own "True Straight Through" perforated internals which lets you keep maximum horsepower and have no flow restriction. The TIG welds are exposed at every seam for maximum weld durability and a great aggressive look. TPV mufflers are densely packed with Vibrant's premium multi-layered sound absorption materials which is what creates a low and deep exhaust tone.
