THERMO-TEC 11246 High Velocity Exhaust Jackets for 4-6 Cylinder

These innovative quick-wrap jackets offer seamless insulation by covering the tubes vertically, ensuring a consistent fit across the entire exhaust system. This unique design allows the exhaust system to expand freely as it reaches operating temperatures, without any restrictions, while also providing additional airspace for enhanced insulation. They can be conveniently applied with the headers still mounted in the vehicle, streamlining the installation process and minimizing downtime.
