2000 Forester exhaust system

[bbenton8]

I will be replacing the intermediate pipe & muffler. I know there is a gasket between the pipe & muffler, but is there one between the pipe & cat converter? (cat converter was replaced a few years ago & I don't remember) The existing rubber cushions look ok, but is it recommended to replace them anyway? Also the haynes book shows a pair of spring-bolts connecting the midpipe to the converter, replacing recommended? (car parts wholesale shows Walker Spring And Bolt Kit PART#:WK35129 MFR#:35129) and what size are the 2 bolts with locking nuts for the midpipe to the muffler?

I've had the car about 3 years and at some point in the past the pipe & muffler were replaced with a one-piece unit- existing is not a separate pipe & muffler

 

so- gasket pipe to cat; rubber cushions; spring-bolts; 2 bolts/nuts pipe to muffler...

 

many thanks:)
