This diagram should help, if necessary the bolts on the cat to silencer sleeve clamps can be cut off if they won't undo, as you can see the three bolts on the exhaust silencer bracket bolt to a hanger bracket, all six of my bolts came out ok but worst case scenario you could always replace the hanger :thumb:

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all
My 2 new silencers arrived today and I need to get them fitted.
Anyone got an approximate cost for this?
I have all the fixings so labour only.
Any recommendations for garages?
Thanks for any help.
I found changing my exhaust silencers pretty straight forward, yes you'll get a few stubborn rusted bolts but if your fairly competent with the spanners then I'd go for it :thumbs:

you have changed the silencers.... I am contemplating the same ... I have engineering skills but not on cars .... having recently acquired my first 996 c2 2003 I am discovering, through forums like this that quite a lot of maintenance, improvement is entirely possible. in fact I am finding myself irresistably drawn to having a go!
My silencers are soon going to need changing and from an inspection underneath, from the block to the tips there isn't a recognisable nut or bolt that could be undone with a socket...they are all shot to pieces ...crumbled away .. I am surprised that the exhaust system is still attached frankly.
What slightly bothers me is that as I go to replace the silencers...
1) break the three studs undoing the three small nuts on the silencer mounting bracket (this is the way to release the silencer, it is said, rather than the vertical bolts) (this bracket is mounted on the block, isn't it?)
2) I disturb the manifold mounting on the engine block and then have a bigger problem in the form of up to 12 broken studs
Any comments/reassurance you can give? did you have to deal with broken studs ...eg on the cat to silencer flanges?

thanks jezgreen .... for the diagram
I am relieved to see that the both sets of potentially problematic studs are 'downstream' so to speak..... namely that they come out with the bit that you are removing...
...eg the flange bolts come out with the cats
and
.... the hanger bolts come out with the exhaust brackets
so there is every chance of dealing with stripped threads/ broken studs on the bench rather than under the car!
