Trying to get crap to run downhill

milkmania · 09-25-2016, 01:47 PM

Well, I'm at Plumber's Rule #1

And the only foreseeable place to put my grey water holding tank is far back passenger side..... BUT!

My exhaust pipe is routed there (hot pipe & plastic = no good)

I was looking at exhaust, and just after it jumps over the axle, it has a 35° - 40° bend, with a clamp just before the final bend.
(Pictured)

My question is, can I unclamp the clamp, flip the pipe over, cut a 5 inch hole in skirt and exit out the side right behind the tires? Or I might be able to flip pipe and turn down at bottom lip of skirt
What are the drawbacks to not exiting out the back? Diesel soot on skirt?

MM,

I've rerouted many exhaust systems that way. Never had an issue. Mind you if you're planning on having living quarters over that exhaust, be sure the body is well sealed to prevent carbon monoxide from seeping in.

First choice is to exit through the skirt, second choice is to exit out from under bottom of skirt.
I WILL NOT dump anywhere behind skirt

But, I hear ya

Turn it out just back behind the drivers seat

Pass! Been there done that
When I got the bus, the exhaust was disconnected at the turbo, but still inline where 60% of the exhaust exited out the rear.... I was amazed I could talk to another person in the bus after I fixed that leak!

If on the curb side, remember that any time you are parked and the engine is running the exhaust will be pouring into your play area. Better to route it out the driver side (mine is just in front of the rear wheels).

NowhereFast · 09-25-2016, 08:12 PM

My exhaust is out the passenger side like that. I get it about the play area idea, but how often would I have my bus running while my awning and everything is out?

bluebird90 · 09-25-2016, 08:23 PM

You may want to check with local laws first. In a lot of places you must have the exhaust exit behind any passenger areas. This is to prevent gasses from migrating into the passenger areas. Your local exhaust shop may know.
Another thought, if you dump out the side you are aimed at vehicles next to you in traffic.
I plan on having a stack at the very back.

I daydream about putting flowmaster or glasspacks and routing it right out the side so i can hear that majestic V8 symphony. Nothing else quite like it for me.

abut i too have wondered the laws about having my exhaust blowing directly into a Porsche window. :chair:

Impossible to exit out driver's side on my bus... The Mitsubishi engine and cage goes from nearly the back of the tires to the rear bumper. Plus I've got fuel tanks on both sides.

I do have what sees like an enormous amount of space down the center of the bus from the axle to rear bumper, but it's going to be tough to route plumbing from outside the frame rail to the center.
Black water tank? NO for sure!, grey water tank? MAYBE... If I can maintain positive angle drop and smaller diameter plumbing.

In cold climate we use the exhaust to heat the water / waste tanks. JMO

I'd do it. I'm going straight pipe from the turbo back. My bus is gonna roll some coal.

cadillackid · 09-26-2016, 08:16 AM

the rule in ohio is it has to be at least behind the rear wheels to be legal... and if you have occupied space it has to be behind that.. however i think the law my designate occupied space as a space with a seat or opening window...

you could easily just call it "utility space" but I have only ever seen people cited for exhaust issues when its either clearly a nuisance or its a cop looking for an easy stop...

I never liked my exhaust exit on the same side as my fuel door only because in a diesel i often leave it run while fueling and it smells bad..

I rthink for you out the passenger side just behind the wheel would be fine unless you do plan to idle when outside the bus alot, but im guessing you'll have the bus off when in play mode.

only thinbg i'll say about through the skirt is make the hole big enough the exhaust doesnt clank around... in columbus some of the IC busses have the exhaust going through the rear bumper and they are the ugliest sounding newer busses as they come clanging down the street as that pipe rattles in the cutout hole.

when i tow, the exhaust does soot up the front of my trailer directly behind the pipe. Plastic gas cans got sooted and i don't think it washes off. it may wash off metal easier than plastic.

i can and need to turn the last section of pipe 180* and it will exit just under the rear side skirt.

i want to dinghy tow and the last thing i need is a car being sooted over.

slaughridge85 · 09-26-2016, 10:53 AM

My original exhaust dumped straight out the rear drivers side and directly onto my motorcycle carrier. I did exactly what you're thinking about except that my exhaust already was below skirt level so I didn't have to cut a hole. I disconnected the slip connector just rear of the back axle and flipped the pipe around so it came out the rear drivers side at about a 45 degree angle. Then I just took the pipe and did a slash cut so it sticks out about two inches further than the skirt. No problems, haven't been hassled about it, and my bike is nice and soot free.

Tango · 09-26-2016, 12:26 PM

Here 's mine...

all stainless up and over the driveshaft...then...

...down and back just in front of the rear wheels on the driver side.
(and being a diesel...also makes it easy to read the smoke)

Yeah man go for it.
I did almost exactly the same thing.
My grey water tank is sitting in that corner.
I cut my pipe after the drop and before the turn but my flip over wasn't quite square and ran it back into where your fender wells/my mud flaps are going to be so I ended up cutting the drop down to make it swivel where I needed it.
Had to get fancy to make a homemade swedging tool/pipe expander for a coupling but all is good
