So I don't want to come across as OCD or anything! but because my exhaust is probably the best feature on the car - I tried to clean them up.
1. I read some forums and bought AUTOSOL from halfrauds and polished outside with microfibre and inside with wire wool.

after autosol
there was pitted areas and carbon etc. so I decided to get the rotary tool out with a soft green grinding stone(silicon carbide i think)(tried wire and sandpaper bits to no avail) which worked really well to get this:

I then bought some 120 / 600 /800 1500 2500 .
it takes soooooo *&^&& long and started raining so stopped.
it seems really hard to get leverage on the inside flared edge and I'm sure there must be an easier way - any advice?
