i have a 90 Gt and just got a Full Mac exhaust. I have a problem with the H pipe, ok on most H or X pipes the have the flange clamp that connect to the headers. this h pipe came with clamps that look like a C with holes on both ends, so im suppose to use 2 of the clamps on each side, but for some reason when i put them together, the clamps together r bigger then h pipe, so wat do i do? i never seen these clamps before and been lookin online but cant find them to see wat im doin wrong.
