VT 800, looking into new drags and pipes. help appreciated..

Hey Folks,
I wanna put on drag bars and mod pipes on my VT 800.

I've looked into few posts about it but still unsure whats best to do.
Hope you don't mind tipping/helping out

ok, so about drag bars:
I don't know what kinda risers to get, remember someone mentioned that least size is 5.5". (think it was Lang, love his bike btw.)
Would 6" or 8" work too?
Any suggestions on where to look for them?
Im thinking black risers with black bar, steel bolts.
Bar with a slight pull back.
Actually looking now at Langs bike, its pretty much how i would like mine to be.

Now, more complex is pipes idea i guess.
I would like to have a bit more rumble but not in favour to torque.
Think oftentimes bikes get crazy loud and loose power due to inadequate mods.
I did that with my XS, don't wanna repeat same experience
Is it possible at all or a bad idea?
I thought of using original headers with heat wrap and cut off stock mufflers to keep in case i wanna put it all back together. I imagine its a simple weld.
Im sure carbs would need re-adjustment and re-jetting, right?
Anyone done this before and wanna share experience?

Im live in Denmark, so shipping from US is kinda steep price since we have to pay pretty high import tax, which kills for me idea of complete set of headers and mufflers.

Anyway,
thought i would share my thinking and see what clever pips got to say.
Thanks!
