Which Headers to buy?

What's the consensus on the best header for the KX 1000A2 motor from a HP standpoint?

I've got a V&H slip on now with the stock headers.

Thanks guys.

any of em are good ..kerker,vance and hines,yoshimura,supertrapp.......kerkers go hand and hand with a kawi and if that red one in your post is yours a nice chrome kerker is worth saving a few extra bucks up for...they are...a show stopper if kept nice...my 2 cents

Well, I have V&H, Kerker, Bassani, and MAC. Of those, I prefer the Kerker and Bassani (based on sound and looks). You already own a V&H, and Bassani and Yoshimura are no longer made and fairly rare. That leaves you with (new) Kerker, MAC, or V&H...at that point it comes down to personal preference...none do an excessive amount for HP increases...they just sound and look faster.
