rain gets the pipes wet, which in turn causes them to expand. bigger pipes = closer to frame = rattle

Yeah it really depends on the catback... Most have pretty good clearance, but there are some that just knock all the time. I've had both. The obx catback rattled a little, but when I picked up the Thermal R&D from gearbox, I had no problem. Its really just the length of the pipes and where each specific company put the bends in the pipe. Even a slightest tweek and bend changes an angle and things just fit too close.

hrmm i still think even after u have tighten up the bolts u may or may not have leakes around the cat-mid pipe and rear piping-mid piping. cause basically all u are doin is pullin it down and the way the piping connects with each other is meant to sit one way basically and any other way may cause a leak. anyways i think the cat is the problem (not sure if thats cat-back) cause some pplz have diff cats or even just left the oem on and had no problem and some did w/ aftermarket ones. i guess im gonna have to try the twist and pull strategy on my exhaust nd see if that works.

i have this issue with my stock exhaust on my 01 hitting my neuspeed x brace. i have put dynamat on the x-brace but that just made it a deep rattle instead of a high ting.
