[Healeys] Exhaust system advice needed

[Oudesluys]

What strikes me is that a lot of people have changed their exhaust 
system for a more free flowing/louder set up and claim they have 
increased power. True/false? It feels faster because of the noise but in 
reallity hardly ever is, because neccessary alterations on the carb side 
are and probably ignition are ignored, not to mention the possibly 
neccessary changes in camshaft timing. These all need to be reset as the 
free flowing exhaust only will upset the overall balance in the engine 
settings.
Just try to drive without exhaust system (free flow in extremis) and see 
what happens. It will seriously affect drivability.
The so called improvement is often observed compared with a rotten 
exhaust in the first place.
