Subject: Lifetime of exhaust manifold?


Hello! The engine noise in my 9000i '89 over 3000 rpm is loud compared e.g. with Audi 100 '89 and 9000 2.0t '97. I've been wondering if the exhaust manifold is getting old and causing more noise on high rpms. It seems pretty worn and rusty in my car even though I can't see any holes. Could it be time to change it or are they supposed to last very long? I have replaced the whole exhaust pipe but the first long one, which still seems to be in a good shape (after 313 000km). Thanks, Terho
