Glass Fiber Exhaust Wraps solve the problem of extreme underhood heat and improve exhaust system performance.Wrapping headers and down pipes is an important first step in reducing unwanted and power-robbing under hood heat. Less under hood heat results in a cooler air charge for improved performance and keeping exhaust gases hotter within the exhaust system helps in decreasing exhaust density & increases exhaust flow.Design Engineering Stainless Steel Locking Ties are the perfect way to fasten exhaust wrap for a easy, clean and professional installation.
