Would i need a modded motor to run this exhaust? or woul i be fine with vf3 reeds, k&n air filter and the proper jetting? also will it be much more of a improvment over fmf?

I believe that you will find that ANY pipe with CORRECT JETTING will give you an improvement in power. CORRECT JETTING is the "KEY" regardless of the pipe you choose. Even a stock pipe will benefit from properly chosen jetting.
Don't get sucked into the right bend,left bend debate.
Trinity is FAMOUS for boasting about dyno figures to sell they're parts. Its as bad a vito's 5HP "power piston"... yea right.
I don't know if you are required to have a spark arrester where you live,but its something you may have to consider.
That price on the pipe in the link is a good price. If you decide to get it,be sure to check the welds for pin hole leaks/poor welds. I've heard that there can be issues.
One other thing...please don't buy a pipe because it "looks cool",or "sounds cool". you'll be cheating yourself.
Purchase a pipe that will create more power with proper jetting! It would suck to drop all the cash on that pretty chromed right hand bend pipe only to get your a$$ handed to you by another blaster that has rusted,scroungy looking FMF and correct jetting.
In my opinion,I would also carefully consider the FMF. A very good pipe! If it was me,and knowing what I know,I would pull that cylinder and head,and send them off to get an "Aggresive Trail" port,and a rechambered head. Just the head alone is impressive! Ask me how I know.
I do my own porting and head mod. This isn't my stuff,but is a good read...
