Listers,
Well, this evening I started putting in my new front pipe and muffler and
so I naturally have a few questions. Context-I'm installing this in a 1974
Midget which used to have a header and straight pipe in it. Now I'm
putting in the stock exhaust manifold and resonator box/muffler set up.
I put the exhaust manifold in a night or two ago with no worries. Tonight
I installed the front pipe.
First question: is one expected to get an absolutely flush fit of the
sliding flange on the front pipe with the flange on the manifold? Mine is
close but not quite. I put a small amount of high temp RTV at this joint
and started tightening the bolts. I got to a point where I just physically
couldn't tighten anymore. Not much room to work in that area is there?
Also, I was afraid to snap a stud.
Second question: the front pipe is just attached at the manifold and about
3/4 of the way to the end of the front pipe using one of those rubber
mounts attached to a bracket. There aren't any more brackets to the car
for the front pipe are there?
Third question: I assume I just use some sealer and clamp at the joint
between front pipe and muffler assembly?
Fourth question: I have another one of those rubber mounts but can't see
anywhere to attach it to the car. All I see are two straight bolts coming
out of the body. One on the driver's side and one on the passenger's side.
Are these the only two mounting points for the resonator box/muffler
assembly? I expected to find a place to mount a u-bracket or something.
There was one auspicious set of two holes almost at the very rear of the
car on the driver's side, but the spacing is too narrow for either the
rubber mount or a u-bracket. Get a smaller mount or bracket? Use the
straight bolts with some sort of bracket?
Can anyone help with how the muffler is attached to the car?
Fifth and final question: I have two round rubber muffler bushings.
Assuming that I use the obvious two straight bolts, can I further assume
that I use one rubber bushing on each to cushion the ride of the muffler?
Thanks for bearing with me. This whole car repair thing is new to me as I
know is obvious to all the gurus out there. :) But I am having a perverse
sort of fun figuring all this out with list help.
Thanks for any answers to my myriad questions.
Can't wait to drive again. Could be on the road Saturday if all works out
with the muffler install and I can get my carb float bowl leak figured out.
New seals and washers coming my way to help with that.
