My Akrapovic had a Carbon hanger. I wouldn't base my whole buying procedure on whether the strap was the correct strap to a type of can, especially when the can is as messed about as this one seems to be. Do Akrapovic make stubbies? if not then the make is irrelevant. You might as well use any can if you're going to modify it from original. Which the maker of this can might have done.
Like has previously been said id want proof of Ivanising and authenticity of products.
Anyone want to buy my Ivanising receipt, going cheap £150
