 Thinking out loud, it seems all the options only have a 2" or 2.5" single pipe, is that enough? It just seems a bit small... | ||

 I guess flow rate idnt that significant as we want torque rather than hp, but it must improve flow. Did you notice the difference when you went 3"? | ||

 I toyed with the idea of twin exhausts and adding an exhaust valve like the F-type so that the second exhaust was only used when full throttle. Vacuum operated exhaust valves were available from Ferraris on ebay, but I didn't have easily accessible vacuum manifold to operate them.

 There are a few options for valves including using one of these: https://www.ebay.co.uk/itm/113559212594 Great food for thought, thanks. | ||
