[Fot] Spitfire 1300 exhaust header

[Robert Scollard]

I recently replace the 1147 engine with a 1296 in my spitfire vintage 
racer and  am having trouble finding a good exhaust header.  After what 
I've spent on the engine, I would hate to ruin its performance with a 
lousy exhaust system. I have 2 questions:

1) What good racing exhaust manifolds are out there?  I've looked for a 
4-1 and the only thing I can find is the Pace Setter.  I've heard these 
are not all that great.

2) Where can get the #1 or, does anyone have an exhaust manifold they'd 
like to sell (maybe a Stahl)?

Thanks
