Exhaust Manifold Recommendation

Hey folks,

I need to replace the exhaust manifold on my 99 TJ. What is the best
recommendation from those that have been there/done that? Looking on ebay
and searching the web I see a wide range of units available.

Thanks!

Jerry S.

I bit the bullet and replaced it with a header on my '99. Good excuse
for an upgrade, and I got a good deal on a Thorley.

Hi Jerry,
You do not say what kind of condition your exhaust manifold is in. My
97 TJ is only now starting to hiss and I am looking at a POR Fire
Sealant 2000 produtct http://www.por15.com/product.asp?productid=7 I
just recieved the catalog in the mail and wa looking at the rust paint
that I have read good things about but I have not heard anything about
this 'exhaust patch'. In any event, it's down & dirty (read that as
chaep) only $15, but I like Bill's $135 product also - depends on your
cash flow and the condition of your manifold.
Good Luck,
Steve
Hey, has anyone heard anything about this Fire Sealant 2000? It's
suppose to handle 2000 degees - huppe or a good product?

While I have not visually verified the extent of damage to my manifold, but
I have all of the classic symptoms. The exhaust noise is loud from the
front, I get a "popping" backfire upon deceleration (more when the engine is
warm) and a strong smell of exhaust coming from the front of the jeep,
especially when the windows are down. It has been a progressive issue for
the last few months, but I have been holding off until the warmer weather
set in so I could do the job more comfortably.

I'm a little worried about the condition of the exhaust studs. They have a
significant layer of rust on them and I am concerned about them breaking
when I remove the manifold. I may go ahead and buy a set of replacements and
an ez-out to have on hand when I do the job. I will also soak them overnight
with penetrating oil before I start.

Any other hints?

Thanks!

I was woried about my ZJ but the bolts all came out with a crecent wrench.
(pb blaster overnight probably didn't hurt)

If you do get one that siezes try more PB blaster on the threads and
tap the end lightly with a hammer/drift to break the crud loose.

Remember, clean both the head and manifold. Don't leave any carbon traces
on the head (a scotch brite pad works good) Bits of sock/papertowel will
help keep crud from falling down the exhaust port. ALthough for the most
part that's only going to be carbon flakes from the exhaust port.

Sounds like you may have the new record:

Yups, that popping backfire sound is what finally made me get off my
ass and replace mine. Only hint I can give you is to get a swivel
socket or whatever it's called. The angles to the studs can be kind of
tough. All of mine came out with no breakage.
