Hey i have a remus exhaust which i need clamps for, i dont know which size to get though. Im not an expert on cars, but i went out and measured the diameter of the pipe, at the tip (it flairs out) its about 3" wide but right before the tip it is about 2 1/4" wide.

Anyone know which size clamps i should get for this application? i dont want to get the wrong size because the clamps needed (wiggins clamp) are crazy expensive
