I had one on my truck, I pulled it off a Massey combine. It had a rain cap on it but it was busted and slipped off to one side so I got a new one for like 8 bucks from the farm and ranch store near me. I hit it with some silver high temp bbq paint(I don't like black stacks, just me).

matters on pipe size. my truck will get covered in soot after a rain or snow storm if i dont cover the pipe. i use a old plastic pitcher. has a handle on it. works great.

I saw just the other day where someone was making and selling custom covers for stacks :tu:

just put the a 5 inch with a turn out on it you dont have to worrie a bout rain or anythang and you can buy the stack its self from napa or orielys they both cary just about everythang for a big truck may have to order it but that wher i get the stack that r on my uncles westernstar

water still gets into turnouts.when does rain ever go straight down.dont put anything on your stack it will scratch the crap out of it and it will look bad.if your worried about it so much dont even put them on

If your stack is black then i doubt the coffee can is going to make any scratches that are going to be able to be seen. Just my $.02.

water intrusion
 

unless you have stacks coming out off top of you engine it would take 2 to 4 gallions off water to to get into your engine.,and if its a daily driver thats not going to happen. So if it's going to sit all summer then put the coffee can on if your driving it every day don't worry about it.

it just keeps the water out so no water soaked soot will come out and cover the truck. that shit is hard to get off.

Not necessarily. Did you read my post? Theres a guy making custom covers (out of leather I think) for them. You would prob have to let it cool down first, but it would work.

really? didnt know that...... prob high as heck

just do a single mitre and use a coffe can thats what i use to do when i cared but now i dont and i blow soot all over the place everytime i fire my truck up after it rains and the rain still gets into the turnouts just usually not as bad as a mitre plus ur beds guna turn black and anyone to sit on your talegate or in your bed will end up with a black A$$ which i find funny:c:
