Exaust "snorkel"?

[workingclass78]

I am interested in adding what I think is refered to as a exaust snorkel - The exaust pipe that comes up the drivers side front of a wrangler. BUT - I do not know the exact name of this part to even begin a search for it.
It is also really cool lookin!

Also - Does anyone have any opinions on adding such a part: Pros Cons etc. I do a lot of 4 wheeling and I dont hesitate to cross water, streams etc. Also worth mention I have cracked my exaust manifold twice this year, is there a way to mitigate the chance of such damage from reoccuring.

thanks for the insight and advice guys.

I think you are talking about a snorkel for your intake. ARB makes one the safari snorkel or somthing like that. I think they kinda look silly, if you cross alot of deep water then go for it, but if not your stock airbox will work just fine. I don't think the intake snorkel would help in cracked manifolds, but then again we could be talking about two differnt snorkels.

I think a snorkel(s) would be a great mod by the description of what kind of wheeling you do.

Intake snorkel would prevent sucking water into the engine via the intake.

An exhaust snorkel would be a removeable extension of your tailpipe that would rise up in the rear of the vehicle. This would prevent water from backing up into the exhaust/engine in case you stalled or slowed down to an idle while in deep water.

No sense doing the exhaust snorkel before doing the intake snorkel in my opinion. If you have an intake snorkel you can keep the RPM's up through the crossing and no water could back up the exhaust.

If going into deep water, it's a good idea to put silicone or even better dielectric grease in all of your ellectrical connectoers as well.

The intake snorkel (or even an exhaust snorkel) won't help with cracking the manifold. That's caused by the cold water hitting the heated manifold. The sudden change of temperature on the outside opposed to the high temp inside is what is cracking it. Can't think of anything to prevent that from happening, other than driving through water that is above 150 degrees.....though I can't see that being a good plan, either......

The tail pipe snorkel is the one I am interested in, though the intake snorkel has a neat look to it, I like driving through deep water, heck I have a tendency to MAX out my Jeep (really), It is no wonder I cracked my exaust manifold. Now I am facing a huge amount of $$$ since my mechanic says that you need to remove the top of the engine to get the new manifold out/in. IS THIS TRUE.

Also, goood point on the water temp being the cause. That in mind does EVERYONE crack their manifold at some point because we all cross water and drive through muddy puddles. Initially I thought I had cracked it by clipping a rock or getting hung up on something - so I was thinking about mickying up a makeshift additional skid plate for areas not covered. so much for that.

Has anyone invented an exaust wet suit!!! : )

What good is it to keep it out of the tailpipe if you're sucking water into the engine through the air intake???

This is why you don't see too many exhaust snorkels.

I'll admit, the intake snorkels are probably so popular for the"look", but they really are a worthy mod if they are needed.

You couls go with a header and wrap it with a special tape made for them. race car drivers use that tape on thear headers. the headers are also not cast like an exhaust manafold is so it should do better in the wet conditions you like to play in. I have to agree with twisted about protecting the components more prone to water damage. You realy need to seal all of your electrical systems. also make sure that you run your vents for your trans, rearend, and front end to a point that keeps water out. if you have not done this task yet it is a real good idea to drain, flosh and refill thoes things before you are faced with spending alot of money for repairs. the cost of repairing thoes will make the exhaust manafold replacement look like peanuts.

Why go straight thru it when you can take the scenic route around it!! :lol:

I've made a couple exhaust extensions for deep mud. The best way is to weld a flange at the end of your exhaust pipe. Weld a matching flange on the extension, then when not in use you can unbolt it. As long as the flanges are thick and flat, gaskets aren't even required. It's not needed 95% of the time, but with it in place it's one less thing to worry about. Just point it straight up like the stacks on a mud racer. As long as you don't let it sit uncovered with the engine off, nothings getting down it.

The manifolds are crack prone anyway. Buy the nicest header you can afford in this situation. For deep water, the corrosion resistance of Borla's T-304 SS header is nice.

Something like giving CPR with an idiot nurse at the controls of the defibrilator (sp?), eh Sparky? :lol:

To add to what whiterubicon said about the diff and transmission filter relocation. That is a REQUIREMENT for deep stuff, but it's still a loosing battle. If you're gonna play in water and mud, change the fluids very frequently. It's expensive yes, but gears are more expensive.

 

[Bounty__Hunter]

Your exhaust manifold cracked because nearly all early TJ 4.0L exhaust manifolds crack, XJ's too. Water had nothing to do with it.

Weld the crack on the stock manifold and then anneal it with some Mapp gas. Seen this done many times and it never cracks again.

If you have an auto transmission I wouldn't worry about getting a snorkel and avoid water like the plague.

stainless steel headers will solve the problem of cracked exhaust manifolds

You got that right! :lol:

transmission torque arm question

I caught word that there might be a recall for any cracked manifolds... I think there is one on dakotas... might be worth checking into?

I have an ARB snorkel and love it. It's saved my butt a few times. You never know how deep it's gonna get. I made the mistake of hydro locking my motor a few years ago which is why I got one. Very easy to install too.
Here's a picture on one on my YJ...

As for an exhaust snorkel, never needed one. As long as you can keep it running and don't floor it while your exhaust is under water, you should get very little water in there. I've heard that if you floor it while under water, you can actually suck water back up your pipe. Don't know how much truth there is to this because if it's a muddy hole, I've usually got my pedal to the floor and never had any problems....yet.

I was told you're fine as long as you don't try to restart it if you stall, also if it's a manual you should try not to shift while your exhaust is under water. As far as an exhaust snorkel that is.

In quick water crossings you're fine as long as you keep it running and don't let off the gas quickly. But what if, to spite your best efforts, the engine stalls and you have another 50 feet of the sloppy stuff to cross? That's when an exhaust snorkle comes into play. If the mud is thick enough you're NOT going to keep the engine running if the pipe goes under too deep and you let the rpms drop too much, and often you can't restart after the pipe gets buried.
