[TR] TR6 Exhaust Manifold

["Doug" <dougfr@comcast.net>]

Old subject but need a little advise.  I'm upgrading my '69 TR6 engine with a
better street cam and porting, etc.  Stock carbs for now.  The original
factory exhaust manifold is cast iron with a single exhaust pipe system.

Would it give me improved breathing if I went to the 73-76 cast iron exhaust
manifold with the dual exhaust pipe system or should I remain with the
single?
