Ok I have gone over countless thread after thread on which full exhaust system to go with on my 07 1KRR.. I have narrowed it down to these 3.. Sato or Akrapovic or Arata.. I have seen the dyno for all of them, but still not sure on which one.. Im looking for the best setup for performance. Any advice would be really helpful.. Thanks

I wouldn't expect much diffence between the three on the same bike and jetted for optimal performance.
I'd go with the lightest myself. Reducing your power to weight ratio puts hp in your pocket as well :)
A mate just bought a TiForce Ti system (everything except the rivets, springs and packing are titanium with billet aluminium flanges) for his Busa. The complete system weighs 4135gms including the muffler hanger. He also bought a full Yosh system which weighs just over 7kg! I intend to weigh it to confirm the Yosh myself though. 3kg on a 300kg/150hp bike is a worthwhile difference in my opinion - and the TiForce is A$600 cheaper than the Yosh. He hasn't had it mapped yet as he's in the country but I'll let you know how he goes with it.

I'm sure any of the 3 would be good. I would actually rate the Akro 3rd of them but it still a good system. I have a Sato system on my bike and I love it, beautiful construction, sweet as blueing of the Ti, and its so freakin light. Looking at the Arata it looks just as sweet.

I have read over and over as well on those three and don't think that you will find a big performance difference. I think the Sato is the best looking of the bunch for what it is worth. I think the labels on the cans of the Akra and Arata are ugly.

I'd believe that. I know I have a different bike but I know when I put mine the butt dyno said it had to be at least 10hp. then I got 6 more with a custom map.

Following up on this.
Just weighed the Yosh RS3 tri system for the Busa. All stainless except the spring flanges which are cast aluminium.
Complete system weighs 6797gms or 65% heavier than the tiForce Busa system. The Yosh muffler with just the support strap weighs 2454gms.
