Toyota and others simply weld the flange down lower on the pipes a bit, allowing them to stick up into the iron upper manifold a little. In the case of a Spitfire, you'd have to weld a little stub pipe onto the lower manifold to duplicate the effect. Not quite as good as making a new one complete, but it should be fine.
As long as you don't go wild with the new tube section, it's not going to hurt flow appreciably. You could even use a smaller pipe section that slipped into the existing pipe without doing much of anything to the flow. The muffler is far more restrictive. Only if you go wild with small diameter pipe sections or sticking it way up into the upper iron manifold would you adversely affect flow. All you're after is blocking the exhaust gasses from going by the gasket, nothing more. >>> Michael Hargreave Mawson <[EMAIL PROTECTED]> 4/5/2005 I guess that answers my question about whether tubular inserts would cause a problem with the flow of exhaust gases. If Toyota and Fiat both design them in, there can't be any real reason for concern. ----------------------------------------------------- The information contained in this communication may be confidential, is intended only for the use of the recipient named above, and may be legally privileged.
