It looks great.
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've got a 3" exhaust on mine and it is a bit loud, probably too loud (MOT advisory last time)

I like the idea to twin exhausts, I'm considering adapting a p38 system.
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"? |

Yes, it sings at above 4000 rpom, but is a bit sluggish below that. I should have perhaps stayed with the 2.5" system I had previously, but I upgraded to John Eales Dakar manifolds at the same time.
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.

That's a very interesting thought, and a good insight.
There are a few options for valves including using one of these: https://www.ebay.co.uk/itm/113559212594 Great food for thought, thanks. |
