I've discussed this on the forum before. My Superspec has the standard twin outlet from the silencer. On the advice of a Club member I actually blanked off one of the pipes with a bung to see if it helped the emissions (a long standing problem with the Superspec). To my surprise the car ran appreciably better, much sharper, better throttle reaction..... Discussions at Car Shows ("why have you blocked off the exhaust ?") seemed to show the the better performance came from increasing the back pressure in the system, which the engine seemed to like. Obviously the exhaust system was never designed or tuned for the engine it was just made of parts that Robin Hood Engineering to get hold of, so the explanation made sense to me. So I would think that increasing the bore size would actually reduce the back pressure and have a negative effect. And the same effect would be seen by removing the cat, as that would also reduce the back pressure. So I will be very interested in the result, but it may not be what you expect.

I'm making progress with the shed

It's that time of the build where I want to start building a completely custom wiring harness for the 100e, but not old is there a lot of wiring in this video, I receive a very generous gift from a subscriber! First up though is making FIVE battery leads, 1 ground, 1 to the FIA battery cut off, 1 to the bulk head connector, 1 to the alternator and last but not least, 1 to the starter! With those out the way it is time to turn attention to the main fuse board, which leads on to the fancy start button set up I want to use! It really is never ending this stuff.
