http://screamingdemon.com.au/index.php?main_page=product_info&cPath=190_194_228&products_id=943 I'm looking to change the exhaust on my 07 GPX250 to one of these screaming demon ones, it says in the description that it fits anything from 07-11. Mines an 07 GPX250 (not the new shape, the old shape one) So just wondering if this will still fit? any problems that I could have if I do get it? Any other screaming demon exhausts I could get which would work around this price range? Also how easy are these things to put on? I'm not extremely good with this sort of thing.
