Aftermarket cams and some cylinder porting would give significantly more power gains for for not much more than the cost of a complete exhaust. Why don't you start there? Afterall, there is nothing inherently wrong with the stock exhaust.

Wrong! It isn't carbon fiber and doesn't have stickers on it!

I would do what GMC has suggested for the price factor.

you want more power out of a 450??

twist the throttle.

but really get the suspension set up. you will be faster.


PS and i hope when you say sound good you mean quiet. the last thing the world needs is another loud bike

I second that. I would my money toward suspension first. After you get it done and get it all set up right you'll be kicking yourself that you didn't get it done along time ago.
