ps
The popular four branch exhaust manifold we do has been improved ,thanks to Freddi McGowan letting us copy his ported head ,the MK2 manifolds are ready ported to a Newmans profile as used on 750 reliant racers in the 70s.
using the manifold as a template you can match your inlet and exhaust mouths to get even more go.
We do a step pipe to make your standard pipe fit the new 4 branch
Designing a full tuned big bore system to fit all Reliants and Bond Bugs , first one should be ready next few weeks
you can see the whole sytem being tested here http://www.youtube.com/watch?v=egv3Z7_C6W4
