304 Y-pipe

Hello CJ-ers,

I'm restoring an '83 CJ5 in which a PO installed a 304 engine. When I bought it, it was equipped w/headers. However, I am replacing the headers w/stock, exhaust manifolds.

The headers fed into a Y-pipe, which looks very similar to the stock, V8 Y-pipe for CJ5. I checked w/NAPA today and they have a listing for a Y-pipe for '76-79 CJ5, but no part # for 1980 or '81, V-8 equipped, CJ5.

Could anyone please tell me if the '76 - '79 Y-pipe will fit my 1983, 304, T176 -equipped, CJ5? My header Y-pipe is in decent shape, so if the stock, Y-pipe is unavailable, I may take both the Jeep and my header Y-pipe to a muffler shop to modify the pipe to connect to my stock, exhaust manifolds.

If it's available, I'd prefer to acquire a new, Y-pipe.

Thanks, Tim

I went through the same issue 5 years ago. My '7 came with fender well headers, which gave me a headache every time I drove it for more than an hour. I too went back to stock manifolds with the intention of going to stock exhaust. The only Y-pipe I could find was for a 304 with a 3-speed tranny. I didn't understand why it would only work for the 3 speed (I have a T-176), and the vendor told me they didn't know why either, so I ordered it anyway to see if it would fit. It did not. I googled and searched my butt off, asked guys here what they did, and the only Y-pipes I found were home made. What I ended up doing was taking it to a exhaust shop, told them my issue, and let them figure it out. They ran separate pipes back to a muffler in the stock position with 2 inlets and one outlet. This let me use a stock tail pipe, and that's it from factory exhaust.

I hope you have better luck.:cheers2:
