Exhaust question

[mudmonster61]

i had a crome exhaust tip on my jeep , from back in the crome era.....so i cut it off with the saw-zaw, back to the first (from back to front) exhaust hanger......well it was shorter then i expected, and now about4" of my gas tanks skid plate of exposed to the direct heat from the exhaust, and when driven the skid plate gets hot....now with that said do you think i should worry about, get the pipe extended out passed the skid or what...thanks

The first thing I do to the exhaust on every Jeep I own is to cut the tail pipe right behind the last bracket. I do this cause I had an entire exhaust get munched when I backed into a rock, it shoved the muffler towards the front and the inlet pipe just ripped a huge hole out...or atually pushed it in:puzzled: and that all happened right after the Sluice Box on the 'Con and there was no repairing it, so I ended up cutting it all off and packing it out in the Jeep with this horrible sounding straight pipe exhauast, total WT:naw: Now with it cut, when I am backin up I know that anything back ther will hit the skid or the bumper before the tail pipe and I have never had any problems with it

soooooooo..............................I say on't worry about it :agree:

When I got the exhaust done on my YJ, I got 2.5" cat-back. The guy who installed the piping (got everything custom made at an exhaust shop), he made the mistake of not bending it well enough around the gas tank. As such, the pipe itself was roughly 1/4" - 7/16" away from the gas tank which is that polyethylene material. You could see where the tank was melting in the shape of the exhaust pipe.
That pipe gets pretty damn hot, so I used a come-along, a chain, and a tree and pulled the exhaust away from the tank by about 2". No more melting problems from the exhaust.

The moral of my story though... that plastic tank is pretty thick and pretty tough as far as heat resistance goes. Just having the exhaust itself hitting the skid isn't going to damage the tank. That skid shouldn't conduct enough heat to melt the tank or anything. If you've never had the tank down then you should have a 1/4" thick insulator sheet of some sorts between the tank and the skid as well.
