never purchased header wrap before and i see they come mostly in 25ft or 50ft packages. I have a hellion kit for my 91gt and want to wrap the headers, downpipe, crossover pipe and the exhaust to just behind the clutch cable. i had some heat issues in years past with stretching clutch cables and im dead set on eliminating those problems. anyone with experience with exhaust wrap give me some estimates on how much im gonna need. thanks in advance.
