Which of these brands will add the biggest power on my Raptauru?

I cant say for sure on the raptor but I have Big Gun on my yfz450 and saw huge gains for my bike.

Barker duals or LTE duals, if you want a single get either Ron Woods or Curtis Sparks, Dr. D and Hindle are good also, i dont like FMF on quads and HMF makes a decent pipe on the raptor but there are better ones out, and Big Gun im not sure how well they are on raptor700s.
