After listening to lots of youtube I've narrowed it down to a set of Two Brothers pipes BUT;
- M2 or M5 and what's the difference?
- Should I get the optional noise cancelling piece?
- What's the favourite finish; Stainless, Titanium, Carbon fiber....
(I was leaning towards stainless or Titanium because I like the look of the current pipes)
Give them a listen if you dare
