didnt read all the way through so sorry if i missed it but spend 6 bucks when you get these and get a set of gaskets from autozone as the ones i got with mine werent even close to the right size...major headache also i had a problem with the lower clamp hitting the lines for my power steering and the tubes were too close together...since u cant take them apart after clamping anyways i just found it far easier to buy a flang kit and welded everything together...i hate exhaust clamps
