We are working on a new exhaust for the 06 10. I am not a big fan of cans non the less two cans under the seat. Started some prototyping tonight and will continue tomorrow. Shooting for the best flow possible and maybe it will wake up a little as expected with good flow. What HP have you guys seen with a good slip on. The bike hit 159.9 STOCK a week ago. This was also on a very strict dyno, "ZX14 hit 161.1" Just wondering what HP we should be looking for??:smile: ???????????
