   right... my exhaust gasket went on the join between centre section and manifold... When it was leaking the noise was not that great at all but it certainly felt a wee bit quicker... Now i have a new gasket and have fitted it all up no blowing or anything like that the revs seem to go up a bit slower...
   
   Someone shed a bit of light?
   
   I know the gasses would be leaving quicker through the leaky bit but surely it should not increase performance?

   I would wonder what would happen if you ran a car on the rr with a system then just off the manifold and no system, I did think about a side exit exhaust before.

   You need a small amount of back pressure to stop the air/fuel mixture being pushed through on the overlap on the cam timing. That was the reason I thought it was needed. Someone correct me if I am wrong please.
