This calculator is a tool to estimate how much exhaust header wrap you will need for your headers, downpipe, or exhaust system. Calculations are a guide only! Actual usage will vary depending upon installation. Tighter installation of exhaust wrap on the pipe results in smaller header wrap needed.
¼" Overlap is recommended for automotive applications, a 50% overlap is recommended for all motorcycle, UTV, kart, marine, heavy duty and industrial applications.
