i put a single 7" stack and i left the cat on the if it rains and i dont cover the pipe will the rain clog or ruin the cat? some one said it can but i have also heard that all it does is blow wet sut all over the truck.

you will always get the black speckle effect unless you putt around till its all dried up. but you will need a 1/4" hole drilled in the bottom of the 90* that turns up.

I am not a smog equipment expert, but it seems that after a few miles and a few full throttle runs that the CAT will get hot enough to burn any lil' unwanted pieces of dookie out the stack.
