Finally starting to get some much needed rain in Corpus Christi, TX. This is how I keep the water out of my single 7" mitre cut stack. I'll drop thousands of $'s into upgrades, but I'm to cheap to get a proper rain flapper.

 

comes with a whole lot of free bubble gum too!

 

Gotta be creative out there.

 

I use something similar on my Farmall H tractor, at least it gets the job done.

I actually have the place that sells those things listed in my favorites. It's only a matter of time before I order one. Only thing I'm concerned about is the wind pushing against it at freeway speeds. I wonder over time if the wind force will bend it back some, and then it might not close up properly over the exhaust stack when it's not running. My stack does come up a few inches above the cab roofline.

 

What I have seen a lot of trucks do (and almost 100% of stock truck muffler systems have this) is to drill a hole in a low spot. On almost any car/truck you'll notice the low spot of the muffler has a hole to allow water/condensate to drain out. What I would do if I had a stack was to install say a Drop (almost like on a sink drain) with a small hole it it. That way when it rains, it will all drain out the hole, and any that dosent will when it has a bit of pressure in the system. A lot of trucks that have straights do this, and it works well. Of course they cover the trailer in black anyway

 

i dont have any problem with rain. i have stacks and no covers. when it goes in it stays. i start it and it comes out lol.

 

I think I'll still get the flapper just because I think the "tink, tink, tink" sound is pretty cool. I'm a windows down kind of guy, and love to hear stuff like that.

 

(You wouldn't if you'd had to drive a real truck for a living and that noise was going on all night a few feet from your head as you tried to sleep).

Who put in the Ravelco for you? I'm debating on whether to DIY it or not.

 

The video above is my truck and rain cap from Iowa80.com. The rain cap has not blown off or been damaged by highway speeds in strong winds or 12s track runs. The way it is made it will rarely close all the way while running. It never tink, tinks while driving normal in traffic or not.

I am very glad I bought it. Wish they had had a plain black one for a lot cheaper, but I have no will power when I see something that I can justify one way or another and looks good.

It does keep the rain out obviously. I do have a fairly high fueled truck so there is some smoke no matter how I try to control it. When it is raining water and smoke will cake up on the inside rain cap and upper part of the stack and will blow a little soot the first time started after a good rain. But light rains there is generally no soot ever and when there is it will only be once after a rain.

 

Rednax, had the Ravelco installed in Browsville at a place called Safe and Sound. They are an authorized dealer, and were almost half the price of having it done in Houston. I think San Antonio has an authorized dealer. The Ravelco wedsite lists authorized dealers around the US. It took about an hour and a half for an experienced alarm guy to put it on, so I don't know if you want to attempt it yourself.

 

RamWheelsBy4, thanks for the info. I'll be ordering one shortly. I just wish they made a black one also. I guess over time it will turn black with soot anyway.

 

I painted mine black to go with my "Back to Black" theme. But to be honest I had to clean all the soot off first to even see the shiny chrome.
