THERMO-TEC 11246 High Velocity Exhaust Jackets 4 cyl.

High Velocity Exhaust Jackets The new quick-wrap high-velocity Exhaust Jackets are an innovative way to insulate and block radiant heat. The jackets cover the tubes vertically allowing for a consistent fit. The fit allows the exhaust system to expand as it comes up to operating temperatures without restrictions and provides air space for added insulation. This product uses Thermal Conduction Technology (TCT™), developed by Thermo-Tec, and can be applied with the headers mounted in the vehicle.
