Just curious: what are the speed limits in South Africa? :-)

Perhaps

Yes, it causes serious vacuum leak. It's actually not expensive to fix -
I went to a small shop that specializes in automotive rubber parts.
Bough a plastic T-piece and and a rubber hose of correct diameter. Cut
three pieces of rubber hose, fitted them onto the t-piece... voila, a
replacement for under 5 bucks. Also check the fat hose that goes to the
crankcase.

Well, you said that you have an exhaust leak - no wonder you have a
rumbling noise. I have that kind of a rumbling noise, too - that's
because the previous owner of my car put in an aftermarket exhaust that
apparently isn't exactly up to the specs. If I clog the exhaust pipe
with a towel, the car gets twice quieter at idle!
