I am eagerly awaiting the arrival of my ASP exhaust system. I will post complete instructions then, but this is what I have so far.
Date: Wed, 6 Aug 1997 17:05:32 -0500 >1. I will need to bolt the stock exhaust w/ cat back on for Both yes. This exhaust bolts straight to the precat, all downpipes fit in
the same position as the precat and will bolt together as well.
>2. Does it require or at least make sense to remove the pre-cat as
well?
If you don't have a computer for the car keep the downpipe on to be safe.
>3. Is anything else required when removing the cat, e.g.- removing Nope, you probably want to zip tie the air feed tube out of the way when
the cat is not on, but otherwise there is nothing to do but bolt it in.

I had to drill the holes out so they were more oval shaped, so I could
rotate the exhaust to get it to line up better. This also prevented it
from banging on the body. Getting it off of the body significantly reduced
the amount of noise transmitted into the cabin.
I also had to go get some gaskets at Pep Boys since the box was torn
open when I received it. I couldn't find the downpipe to midpipe gasket,
so I reused the old one. You might be able to find one at a big exhaust
shop, or make your own (see below).
I used a standard 3" header gasket for between the midpipe and the
catback. --Steve

gaskets. It comes in sheets about 6" x 14." It is not all that easy to
work with, but having it around has made me feel like a king because I
no longer have to worry about finding suitable gaskets for my non-stock
system. I wouldn't use it for an exhaust manifold, but I have had good
luck from the turbo back.
