Overview of an exhaust install. The exhaust paste used was Wurth. The exhaust band clamp used was purchased from Moss Motors. It is a 1 7/8" size. The pipes are 1 3/4" but the bigger clamp is needed to fit over the pipe where the two joints intersect. I recommend loosely fitting everything before fully tightening down. This particular exhaust kit was purchased from British Parts Northwest and there were no issues with fitment.
