lmfao sorry man your not going to have 235hp! haha I needed that laugh today sorry hehe
The bike has 229cc = 15 HP so your not going to gain cc's by installing that exhaust but you might gain .2 HP
the only way your going to gain any power out of these motors is to get a big bore kit and there is no one making them. I did find a site that claims they have an over bore kit but they never responded and I emailed them 10 times.
