When i got my bike, the exhaust was powder coated black, if you look at the picture you can see the colour of the rear pipes i couldn't get to till i took it out today. Harpic Max 10 the same one in the picture is the best cleaner ive used. as soon as you put it on you can see the reaction happening instantly.
