Exhaust silencers.

[etlddle@domain.elided ( David Luke XL/EE )]

Hi all,

I think I've blown a head gasket (maybe 2) due to blocked silencers.

The car has a rover V8 with 4 branch manifolds, custom downpipes, and
everything else standard Stag.

They are stainless steel, very old (7 years at least) and I think full of
crud.
The rest of the Stainless system is fine though. Can I get 2 silencers
by themselves, if so from who and at what cost?

Ideally I'd like uprated silencers.

Thanks in advance,

Dave Luke (Rover V8 1973)
