Review on Heatshield Products 325001 Inferno Insulating by Chad Mills

I wrapped the exhaust pipe for a Caterpillar C-15 diesel engine in a Country Coach Magna Chalet to improve fuel economy. Together with the insulation of the intake pipes before and after the intercooler, this should lead to a significant increase in efficiency. The Inferno Foil was easy to install even with the contortions required in the tight engine compartment!
