Why spend more? The Mach V exhaust wrap kit gives you two 50-foot rolls of our house-brand 2" exhaust wrap, ten stainless steel ties, and a can of high-temp silicone sealer spray, all for about half the price of the brand name kit! Wrap headers, downpipes, and up pipes. Reduces underhood temps, and keeps exhaust heat in the exhaust where it belongs, to increase flow and exhaust velocity.
