Welcome, good morning, today we're gonna start working on our project beetle 1969.
Couple things we have in store today, main thing is to get this thing running and running well.
First thing we're going to do this morning is change out the exhaust.
It has a couple exhaust leak that we noticed. Hopefully it's not coming from the heads and it's
just coming from the exhaust.
So were going to swap that out and then we're gonna get to some other things
later on a video or a separate video perhaps as well.
Alright first thing we're going to do is disconnect the negative side of the battery.
Anytime you working on a major project on a car
disconnect the negative side of the battery that way you're not gonna short anything out inadvertently,
touching the positive wire to a ground and creating a bad electrical fire.
Alright first thing were gonna do when removing the exhaust is pull off a couple,
typically 13 millimeter, nuts on the exhaust port.
There's going to be 2 per exhaust port.
2 left, 2 right, back, front, so a total of 8 nuts there.
Plus we're going to go ahead and pull off the exhaust clamp on the bottom side.
Those are typically 10 millimeter nuts on the top and bottom of the clamps.
So pull all those off and that will allow us to get off the
exhaust and the j-tubes on this model as it does not have heater boxes.
Alright now we got the four exhaust nuts off the exhaust ports and the j-tube clamps are loose.
We're going to go ahead and pull off the muffler relatively simple.
Yank and pull and there is our old looks like a Tri Mil 2 Tip GT.
One of my favorites just because it give a good ground clearance but were going to switch out
to a different style two tip GT exhaust today.
By no means do you have to pull off the tire to remove the j-tubes we just did
so it's easier to see in the video and/or photos.
We're going to pull off the two nuts here.
One at top, one at bottom ,we'll do this both sides.
That will allow us to pull off the j-tubes and replace these were here as well.
Alright with our new exhaust gasket,couple spring washers and new copper lock nuts for the exhaust.
We'll go ahead and put the j-tubes on now.
There is a left and right on the j-tubes so don't confuse them.
Anytime you're fitting in an exhaust,
until you get everything attached the hear boxes or j-tubes
the new exhaust pipe a muffler or header or have you,
you want to put everything on loosely. Get everything test fit,
make certain all the pipes are snug together
j-tubes into the header et cetra, before going through and tightening all your exhaust nuts.
Alright on most aftermarket exhaust,
the heat risers which are made to keep the intake manifold on a single carburetor from icing up,
the actual tubes are not drilled out.
So what we'll do now is drill them so the exhaust gases can actually get up to the
intake manifold and keep it warm.
On the exhaust heat risers you want to have one side
larger than the other so that you actually have some cross flow.
If you have the holes the same size the exhaust gases will just kind of battle each other.
If one side is larger than the other it's going to overpower so the exhausts will actually
flow from one port to the other throught the intake manifold keeping it warm.
Installing the muffler is just a matter of going ahead and first lining up the j-tubes down below
with the gaskets and lock-ring already installed.
Make sure you have fresh exhaust gaskets and then we're gonna use the same
eight-millimeter spring washers
and copper exhaust nuts that we had before. We've got everything lined up
and on all the exhaust ports so now we're gonna go through and tighten down all the nuts
at the heads and then we'll put on exhaust clamps on the bottom tubes.
All in all we're all done here.
We've got a new exhaust on, new j-tubes, new clamps, new gaskets, new copper exhaust nuts.
This thing should be leak free and should get them down the road quietly now for quite some time.
This system is a black system so this paint will burn off fairly quickly.
Keep that mind if you are ever getting a system is not ceramic coated, chrome plated, or stainless steel.
The black paint it's gonna burn off. Installation was very simple and
taking the other one off was very simple as well none of the exhaust studs on the head broke which
definitely make life easy. If those do break we do have replacements available the hard
part of course is getting the old ones out.
Often times you're gonna have to drill out the head put a helicoil in or otherwise.
