Now, before I started this project over 4 years ago, I asked
every expert I could find, all the newsgroups, etc. I could
find no one to say if this had any negative consequences. I
have personally tried this for over three years, and I also
have had no negative consequences.
Undoubtedly, a huge source of noise can you your mercedes exhaust,
especially if it's as old as the are, and you live in a state
with snow, and therefore, SALT! When there is significant temperature
drop, moisture forms, where there is moisture and heat and metal.
we get RUST.
This is a replacement exhaust AND Mod.
Replacing your own exhaust is pretty easy and intuitive. There
are no special tools required. I used a Racket, Wrench, Hammer
and of course, 4 car jack stands and a 4 ton jack. It's much
more easy to work under a car when it's up 2 feet.
There are (3) Three parts to your exhaust
1. Header
2. Resonator
3. Muffler
4. You will also most likely need new 4 exhaust donuts. There
is 2 kinds, the "Soft" and "Hard". Get the
HARD ONES. I used the soft ones and they failed in less than
1 year. How embarrassing would it be to have your exhaust dragging
on the ground behind you?
They run about $100 each-new. I only replaced the resonator
and muffler. This is because it's only when the heat drops dramatically
that you get moisture and rust, and this usually after the header.
Just look at your, it's usually not the rusty. But if it is,
replace it! I got mine off a wrecked mercedes, that had it on
for about 300 miles, good enough for me.
1. Jack up your car, put it on 4 jack stands.
You may want to prop the Exhaust up on some wood blocks, so
it doesn't com crashing down.
2. Take off the two big bolts at the end of the header.
3. Cut the donuts holding the muffler up.
4. Move out of the way. :)
Now it should come crashing down and you can see how bad it
really is:

5. Now you just have put them all back together, two people
is a real help to hold up the muffler when you put
6. You will need to also put on the 4 exhaust donuts. It's
intuitive.
This may quiet down your car quiet a bit, but I went one step
a further.
If you are observant, you will notice two things wrapped around
the pipe, left of the resonator. These were my test strips for
my 3M Heat/Sound shield project. I was testing it shiny side
in/shinny side out to see which one lasted longer. Read
on about the MOD I did to use the 3M stuff.
