dmc comparison question

[Johny_Ringo]

So im lookin at DMC dual exhaust and basically IM starting with a stock raptor I dont plan on to much more then the big 3 but who knows sometimes things happen.
My question is if anyone knows should i get the 700 twin  http://www.dmc-on-line.com/index.php?main_page=product_info&cPath=67&products_id=182  which is what the web site tells me or should I get the force 4 http://www.dmc-on-line.com/index.php?main_page=product_info&cPath=67&products_id=331 which is suppose to be for more modifications. I plan on racing so I need to keep the db down but what im really wondering is could the pipes really be that different that i shouldnt just spend the extra 30 and get the f4 in case i got the itch later or would I be getting alot less HP out of them?? Just a raptor noob askin a weird question

I would get the Force 4s, you'll appreciate them more in the long run.

The pipes between them are routed different. The afterburners make less power, but can be found cheaper.

we run the FORCE 4  duals on bikes with nothing else but intake and fuel controller and they work awesome...all the way up thru the mid 80's hp range
