88 CRX muffler no threads bolts question
 

Hey Guys,
Here's the deal, am a girl and like to do minor repairs on my car.
(such a high to get a problemed fixed myself), well, just noticed my
muffler on my 88 CRX si has rusted out a rather large hole. So by
taking a look underneathe, it appeared that 2 bolts needed to be
removed and the muffler and the small pipe leading to the front of the
car would just come off.
Well I have been trying for a long time to get those 2 bolts off.
Wasted a lot of liquid wrench on them to no avail.....when I noticed
the bolts do not have threads on them.

They have springs on the front of them and no threads on the back and
are held on by 12 mm nuts. It's located right behind passenger side
rear wheel, 2 pipes adjoin with an oval type gasket/connector thingy ma
jig. What is this about? I am kind of annoyed at this point. It
seemed like a simple 1,2, 3 job, but no.

Anyway, can you seasoned Honda guys give some advice? Is it possible
to get the muffler off easily or should I just take it to the shop.
Man I hate doing that. I really like fixing it myself.
Anyway, thanks so much.
Oh my car is 1988 Honda CRX Si all stock. 5 spd, 139k miles, 1.6
engine, red, black interior, sunroof, a small shopping car dent in the
right fender....... :)

Smiles,
