The truck I'm looking at has 4 or 5" stacks and was wondering if they aren't covered in the rain to prevent the build up of water in the bottom of the exhaust doesn't that cause corrosion etc.. I'm thinking it can't be good for the engine either right?
The water can only go so far up the pipe....and usually when you start it, it'll blow all that water out of there (along with a bunch of soot and crap)
I'm sure drilling a hole in the bottom could work but I was just wondering if it would affect the engine due to moisture in the pipes or not before driving to PA to look at the truck as I'm in VA!!!!!!!!!!!!!!!
drilling a hole in the bottom of the pipe will just make it rot out faster.
with the weep-hole in the first exhaust, the pipes only lasted 4 years. the second set of pipes lasted 14 years.
the current pipes on the 88 are now 2 years old, and still look like new.
what does not get blown out at startup will evaporate as soon as you start driving and get the pipes hot.
as ghunt said, the only down side to stacks and rain is the black spots all over everything in a 6 foot circle on first fire-up.

Including your own windshield, side windows, as well as door handles But yeah, I always advise my friends and co-workers to not park on the right side of my truck if tis gonna rain, as no matter what color their vehicle left the factory in chances are it will be nicely black if I have to leave before they do...
What happen if you forget to take the coffee can off before you start it? I'm assuming it just rattles around but if it comes off you might wish you had black soot on whatever that can lands on instead.
We put cans on our tractors stacks and sometimes we forget them but they do not pop off and go flying they maybe go 2' higher than the stack is already. So my guess is it would land on the cab and roll off or land in the bed. Who knows what can happen though. I think it is a good idea non the less.
I actually use buckets because my stacks are too big for coffee cans, but I know several people who use a plastic container like you would get cottage cheese in. You can spray it with primer and it doesn't look too bad, and if it goes flying it won't tear anything up.
I used to have a 350-powered stepside C10, I ran two 2.5" stacks up behind the cab, and I used to cover 'em with 750ml Mountain Dew bottles cut in half. When tis just rain I'd take 'em off before I fired it up, but throw some snow and them bed steps before the fenders got real slippery, so I'd just start the truck and while the high-idle was doing its thing I'd go and collect my "raincaps" - usually they'd be either in the bed or very close to the truck, but a few times in windy weather I had to walk a bit to find them... which is exactly why I used MD bottles, green is much easier to spot in white snow

I have a turnout stack, small one too, you'd think it would be harder for water to get in - nope, it fills up just fine, then shoots all that nasty some good 10ft away! Add some wind tho, and guess where everything falls again.

At least it all goes in one direction to the side rather than up and all over, right?
