2000 Wrangler Exhaust Manifold to Pipe Gasket

I have a 2000 wrangler with a 6cyl (I do have to use 1999 parts on the front axle).
I have had a exhaust leak for a few years and decided to fix it. The leak seems to come where the manifolds let in to a collector pipe.
the exhaust has two 3-1 manifolds then a single 2-1 pipe and eventually to cat and muffler. The problem is where the two 3-1 manifolds dump into the 2-1 pipe. I cut the bolts off and got everything apart but found no remenants of a gasket? I am expecting some sort of gray doughnut looking thing to be squeezed. I cannot find a part on the interweb and autozone already ordered me the wrong part.

Question: Is there an actual gasket there or just a break line flare type connection? And if there is a gasket, does anybody got a part # ????

to The WF!

Many newer exhaust systems have the doughnut integrated in to the pipe as it goes down to the next pipe. Take a look at where it connects to the collector and if it's rounded then you're good without it. If there is a space after the two are mated then you need the doughnut.


But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. James 3:17 (KJV)

Welcome to the forum!
My son's '00 4.0 doesn't use a gasket between the manifold and the front pipe. As mentioned the manifold surface is convex and the pipe is concave. The clamp is designed to apply pressure evenly around the surfaces sealing it up. Before reassembling remove any corrosion from both surfaces with a wire brush or similar.

Just FWIW, my "99" does use a doughnut type gasket (called a Seal Ring in the FSM) between the collector and exhaust pipe. When I replaced my exhaust manifold, I bought a new one at Napa.

I think 99 are different manifolds than 00 and most part stores want to sell me the gasket for that style. Thanks all!
