1980 cj5 258 front pipe

I am needing a new front pipe but am not having very good luck finding one for the 80 Cj5 258. I do have the '81 and later matching exhaust manifold and air intake, that I have verified here in the JF.

I am having a tough time finding the front pipe for it. I did find a previous thread that it was a walker # 44172. Well, no one has that and no one can get it. I did find a walker # 44872 and it looks dang near identical:

http://www.amazon.com/Walker-Exhaust...s=walker+44872

Anyone have any ideas or suggestions? I am getting a new exhaust system installed on Friday, soup to nuts. The muffler shop guy recommended me trying to find a front pipe for him because if he has to make one, it wont last as long (thats all according to him, and this is a very reputable, highly recommended muffler shop).

I am gonna go with an all stainless magnaflow, the lowest resonating one they make, fyi.

I don't know if this helps, but when I swapped the newer style intake/exhaust onto my CJ the existing front pipe bolted up with no mods needed.

Thanks for the input....but my front pipe and its flange are in terrible shape and need to be replaced. I am thinking the one I put a link to will work, but wanted some more input.

I think a competent exhaust shop should be able to fab that piece. No?

Sounds like he's being lazy, to me. My shop fab'd every piece of pipe from the manifolds back.

So if the factory pipe lasted for 20+ years, how long of a time would be acceptable,10 years? I'd have the muffler guy fab the piece you need.

This is what was done on 3 of my Jeeps, the shop made all the parts from the manifold back. If Longevity is a concern , have the pipe made and take it home and paint it with hi-heat header paint and follow the directions on the can.
My guess is the pipe will outlast a ordinary Aluminized muffler.

I just picked up a nice 258 with a heddman header, offenhouser intake and holley carb out of a 1980's cj with manual trans. I was hoping it all will drop in place into 1982 scrambler with auto transmission. Is there a different header for auto's and stick ?

44872 was the one I bought for my 1984 CJ7. They should be the same. The only thing I can see that might be different, it would be the tube for the air tube going to the catalitic converter. I just welded a plug in it. A cleaner instalation would have been to cut it off and weld a plate over it.

I'm not sure what tomorrow will bring, but it can't be any worse than what I've already been through.

CJ 7 exhaust

I'm having the same problem for my 1979 CJ7. The Walker 44872 doesn't have the little bend at the muffler end. Is there a true part or do I just need to bend it?

DrBond...

I gave up looking for a true part number because I wanted to move forward with my Jeep project. I had the local muffler shop make one for me while they were replacing the exhaust system.

I'll be in the same boat soon. Do you mind me asking how much they charged to fab the frontpipe?

Well, I am not sure...

I purchased an entire exhaust, from the manifold to the tail pipe. Since they were doing all of the work, I think they kind of "threw" it in with everything else. I am trying to find a receipt for the work they did, but to the best of my memory, from the manifold, new frontpipe, 2 1/2" exhaust, magnaflow muffler, new hangers, and all welding was under $400...

So to answer the question, the front pipe wasn't much at all...

I will keep looking for a receipt.
