MagnaFlow offers stainless steel exhaust band clamps. Compared with conventional U-clamps and flat band clamps, these high torque clamps offer a much tighter seal by using a reaction block that transfers bolt torque into clamp strength assuring a tight seal all the way around. With the addition of these exhaust band clamps, you can drastically cut down the installation and removal time of your exhaust system. MagnaFlow clamps are available in various sizes ranging from 2" all the way up to 5" and backed by MagnaFlow's lifetime warranty.
