Thanks for the replies! I built some stacks that simply attach to the stock stacks in the box. They are almost 3 inches long. I still have the (clean) stock filter and snorkel in place but the fire guard screen has been removed. I am still planning on trying the header pipe since it is just laying around and i can weld so cutting and experimenting will be fun. I dont know if the stacks have helped any but it feels a little better down low (may just be in my head) but i do not have a DYNO. I have really tall gearing on the bike along with the opened up stock exhaust and shimmed needles. I ran against a friend with a totally stock 2009 Ninja 250 and he could not beat me and i could not beat him. He is a newer rider but weighs 40 lbs less than me. Performance does not seem to be less so i will keep experimenting!
