Spitfire Sports Exhaust

[Alan Coleman <alanco@sybase.com>]

Hi,

Rimmer Bros. has something called a Sports Exhaust for Spitfire on their web 
site. 
Does anybody know more about it?  Sounds like a header.  Is it?  Does it just 
fit 
on existing exhaust parts?  I'm looking for something that improves exhaust 
without 
requiring massive custom fitting (ie something I can do in my garage).

Thanks,

AC
