Dan,

 �It looks like you have a good handle on this modification. Will you 
will delete the booster?


As for trashing parts, if you have the room don't. Can't speak for the 
core value of the MC and Generator but at least one of the two factory 
exhaust manifolds is specific to the Tiger - _if I'm recalling 
correctly_. It use to be cast manifolds were considered a toe stubbing 
nuisance but I'm quite surprised at what people are asking for them 
these days as they regard 60's/70's cars across all brands. Some prefer 
the cast manifolds on the Tiger rather then deal with _potential_ leaks 
with headers. Or some build to originality and would seek the cast 
manifolds if the car they have has previously installed headers.
