cherry red exhaust
#11
They symptoms your are describing, are realated to a couple of things. Usually glowing headers or exhaust are due to extreme load, driving wot for prolonger periods of time, or due to a very lean fuel mixture. I find it hard to believe you were driving wot, and romping on your jeep soo much that it made your exhaust glow. So I would lean to either a messed up air/fuel mixture, or possible a clogged cat not letting enough exhaust through, making the exhaust gas bunch up inside, letting it sit there to heat up the metal. My evo used to glow on the tubro and the manifold, after massive highway pulls to over 140mph, but never just normal driving. If I was a betting man, I would say its due to the cat.

I've never noticed any glow from my JK after being on the highway and then pulling into my dark garage. I would get it checked asap. The first thing I thought of though (like some others) is a converter issue.

X2....Get that checked out ASAP. I would hate to hear that it caught fire while you were driving.

haha, I had a Porsche 930 turbo with a ton of mods, including a larger turbo, stainless eqaual length headers and I ran a straight pipe out of the turbo. When I hit boost, the whole system would glow as bright as a brand new traffic cone.....and then belch a 4 ft stream of flames upon throttle closing. But that was a 450 hp 11 second turbocharged car... not a 200 hp nuthin muffin v6. Surprised that your jeep is getting that temps. No wonder the manifolds warp
1989 930 5-speed
13.6 1/4 time....
Sounds like you spent way too much, on way too little my friend.......

If it is indeed the cat then it should be under warranty - emissions warranty is a lot longer than the bumper to bumper or powertrain warranty WAS (3/36???) - I think the emissions warranty is like 8/80?? It's in the manual..
Since you just said 10MPG then I'd put money that it's the cat that's breaking down... Any dips into cold water with a hot converter?

your jeep has a serious fuel problem and it's not running lean. It's runnig way rich, the fact that everything is red.
It could be an injector problem, timing problem or a number of things. What right now the CAT is eating it all and will burn out.
Be careful as you could lite your jeep up in flames.
I find it hard to figure that the check engine light is not on.

But on the flip side, if his mixture was really really rich, for some reason, that could clog up the cat, and cause more backpressure then required, cause exhaust gases to get caught in side the exhaust making the mani glow......
