Stupid Stacks Question
Got a question about stacks that is probably a dumb one, but here goes:
For you guys with miter-cut stacks, do you have to do anything to keep rainwater out when you park your trucks? Not sure if you put a drainhole in the pipe or cover 'em when it rains or just don't worry about it, or what...
Thanks in advance.

Three ways to go:
Cover them with a coffee can or similar.
Drill a weep hole at the lowest point of each stack or a low point in the system.
Start her up and watch the people run.

A couple of points on the weep hole thing. Depending on your use, they can be both illegal and dangerous. Illegal because no leak in the piping system is allowable, hense the closable weep holes on some big trucks. Dangeous because if you should go to sleep in the truck you have two exhaust leaks under the system.
If you are just using the truck for passenger use I don't think anyone cares but if you use it commercially and get a full DOT check, some inspectors are really hard on leaks of any kind. On my last big truck, in Missouri, the inspector spent more time looking for exhaust leaks than the rest of the truck.
The water entry will never hurt the truck, it could never get enough to get to the engine, but you may have the wet spatter problem that some have.
I have had several rain caps, never would waste the money to get another one. They are not only noisy but the wear out fast and do not operated well.
I have seen one system that welded a 1 1/2 pipe a foot or so long, to the bottom of the system, to allow the water someplace to go until the heat evaporated the water till the next parked rain.

leather/vinyl raincaps
I've done alot of light and heavy duty towing for various companies in the area. You can buy various size leather/vinyl rain caps with velcro or loops to attach bungie cords to. Any towing supply company will have them and they're fairly cheap. They're required when towing due to the fact that when a truck is being towed from the rear, the air is being forced DOWN the stacks through the exhaust fins in the turbo and the impeller will rotate backwards, and most of the time the truck engines are not running.
So guess what. Engine not running= no oil lubribcation to turbo while turbo spins which = TURBO FAILURE!!!!!
Here is one site in Canada that you order them.

Here's one of the companies I worked for.

Then again, my truck is black, so maybe the splatter wouldn't even show up on it?

Hey Chris!
Holes work well in the 90's, plastic beach buckets and bungees from Wally World are great (and cheap) for overnight and so forth, and soot is easily taken care of with soap and water.
