[Healeys] Exhaust system advice needed

[Eric (Rick) Wilkins]

I understand what you're getting at. The "what" is that 50 years later  
we know that a Healey came from the factory with a fairly restrictive  
exhaust system. We also know that by increasing flow, we can gain a  
bit of added horsepower--without changing anything else.
Sure, with newer cars being tuned pretty well from the factory, gains  
from a simple exhaust "upgrade" are very limited. It's not rocket  
surgery.
Get a dyno, measure a stock spec Healey, and measure one with a  
freeflow exhaust. I'd bet that you'd see an improvement.
