It's a side valve so performance is subjective! It has other mods as well, all done at the same time so attributing gains to any one thing is impossible. What I can say is that it is very torquey and will run at higher speeds than before the work with a feeling that it is doing it easily, little throttle being required to do so. Before it was hard work above 55ish with foot to the floor! Cruises at 70 nicely now. One thing I did notice was where the hot bit was (you know, the story about paint a white stripe and where the burnt bit ends is the correct length), it's at the end of the manifold. Weird. Hope that helps. Oh, it sounds like a barrel of wasps!!!!

A quick google search for Austin 7 race exhausts shows the tubes being probably 4ft long (which is about the only sidevalve I could think of which might have race-spec exhausts for), so it figures..

Apart from the long, and current, history of racing ford sidevalves? 😉 No idea what they use these days though, i just put an aquaplane on mine.

They may be a bit agricultural but i really enjoyed squeezing power and economy out of the old sidevalve.
