Description Reviews MINI Cooper Downpipe Clamp. This is for Cooper's only not an S. Find the S downpipe clamp here! Exhaust clamps take a real beating on any car. They tend to rust because they are bare un-coated steel and often get very hot and cold many, many times. They also see all the dirtiness that is on the road surface.... water, mud, & snow... that all helps speed that rust up. If you're adding an exhaust system more than likely you're going to need a new clamp. This is a good item to have on hand just in case you need it because you're not just going to run down the street to your local auto parts store and pick one up. Be ready, and do the job right the first time. MINI OEM clamp with metal gasket already in place. MINI Torque spec is 18.4 ft. lbs.
