Hi, new here. I've been looking around and this seems to be the best place I've found so far for help. I'm not that car savvy, sorry, and I have a question about the fuel tank for a 2k1 Cher Classic. I have dual exhaust, but not quite the proper way ( So I'm told.) The 2nd pipe splits just past the rear axle and curves around the fuel tank to the opposite side of the main pipe. Fuel tank type is the HDPE/DPE/EVOH. The secondary pipe is maybe a half an inch away from the tank. Though not as much exhaust goes out the 2nd as the main, it does still work. Note: No heat shield is bordered around the secondary pipe.

My question is, will the secondary pipe, being so close to the tank, cause any kind of major threat to over heating the tank and causeing a fire or one hell of a show on the highway? Note: I've been driving like this for 4 years and just now noticed it when I was putting on new pipe brackets.

Personally, I'm not that concerned, but my folks are. I'm looking for some other thoughts on this, and what better place than one that has a bunch of people that know jeeps?!

Thanks.

EDIT: Since I'm here, and hoping you all are nicer than the last forum I tried, what would be a good choice of shocks? All 4 of mine are all but useless. I don't do much off roading sadly. It's mostly used for highway driving...which considering our highways, could be considered off-roading.

This is probably a better fit for the street and performance forum here. Non-Tech Off Topic is more of a BSing forum, talk about random stuff.

For your question, I'd imagine it would be helpful to get a thermometer and get a temp reading off the pipe.
 
x2 on checking it with an IR thermometer. Something fairly simple (and cheap) that might calm the folks down, is to throw some exhaust wrap on the pipe. I'd probably do that anyway; you know how people drive here, getting rearended is almost unavoidable.
 
yeah this thread should be moved to a tech forum.

Cars and trucks with V8s tend to run dual pipes because they have two separate exhaust headers, one on each side of the engine, and they can run two separate pipes all the way back.


Our I6 has a single exhaust manifold so there's really no reason to run dual pipe vs a fatter single pipe.

In your case with the split that far back it's certainly not doing a damn thing for performance, it's totally just cosmetic. You could just hack out the Y and put in a straight section. You could leave the other exhaust tip so it LOOKS like dual exhaust, if you like.

I agree with Darky, get an IR thermometer and check the temps of the pipe and the tank.

Unless you have some reason to care I'd get the cheap shocks at the local parts store.
 
Thanks for the help.

Yeah I know it's pretty much for cosmetics. It is a normal straight pipe, but the previous owner put it on there.

I'll look into the thermometer and test out how hot it really gets.

Sorry for putting it into the wrong forum. Worked all night and didn't sleep hardly at all, wasn't focusing really, lol.

Thanks again.
 
I wouldn't run that second pipe so close to the tank w/o a heat shield. Since it really isn't doing anything for flow (you said it splits after the rear axle), just have it removed and the hole patched. That would be the best option.
 
Thought about that, but I want to try to keep em. What's the danger temperature on the thermo, when I should really consider taking it off?
