I got my upgraded car back today.
First thought: what have I done! It now sounds harsh and obnoxiously loud. Like a Harley with a loud exhaust.
But by the second drive this changed to "maybe it's ok..."
And now I think I like it. It is certainly quicker. I hit the Rev limiter several times, which I don't remember doing before. The dealer says 15hp more, which is quite a lot if you only started with 85!
There is new noise though. I have learnt to ignore strange noises as part of Morgan 3 wheeler ownership. But this one is very loud and sounds like metal on metal, right from the new exhaust mountings near the (expensive 2014) heat shields. Hmm. Usually these things go away on their own I suppose.
