Rep Power: 0 Sound / Vibration when I hit a puddle?
-I recently put on a random tech cat and Greddy cat-back. Eventually, all was working well until I noticed that whenever I run over a puddle, I notice this loud, clanking vibration that sounds like it is coming from the front of my exhaust / the cat. The sound also gets much tinnier and basically sounds like crap. This happens immediately after I drive through a puddle, and takes about 2 min of driving before it is back to sounding normal. Again, it happens EVERY time I drive through a puddle. It hasn't really rained here in Cali for quite a while, so I'm dreading the first rain. Anyone have any ideas what this problem can be? Do I not know something about Hi-Flow cats? Thanks

Rep Power: 335 This is normal and is called thermal shock.
When the exhaust is hot the metal expands, when it suddenly hit cold water it contracts rapidly and will need a minute or two to return to normal.
When it rain water hits it all the time and this will not happen unless it is slightly submerged in a puddle
