Wrapping headers and down pipes is an important first step in controlling unwanted underhood radiant heat. Keeping exhaust gases hotter within the exhaust system helps in decreasing exhaust density and increases exhaust flow. This improves exhaust scavenging resulting in cooler air intake temperatures for an improvement in performance and a gain in horsepower. Design Engineering stainless steel Locking Ties are the perfect way to fasten exhaust wrap for a easy, clean and professional installation.
