So having decided to move over from an AKRA end can on a std set of headers to a full system I phone a couple of Berg dealers (UK) to ask about geting a used or new full system. Very friendly helpful responce 'yes got one around here some where will get back to you with a price'. Followed up...

Running an Akra ti end can on standard header pipes at the moment. Is there any point in swaping the headers? If so what should I consider swapinmg them for, and where is the gain, powere? weight?. Oh and where is a good place to look for a decent second hand set?
