Okay, so the new muffler arrived today, and the place where it connects actually splays out a little so that the OEM exhaust pipe very snugly fits inside it - NICE! The two pipes overlap by about 1.5 - 2". My question is - should I use one exhaust clamp in the middle of the overlap, or two clamps each about .5" from the end of the overlap. Perhaps a more important question too - how tight should I tighten down these clamps? Should they just be "very tight", or should I be trying to crimp the metal pipes together?

Thanks
