I bought the same system and it rocks! It had 200 miles on it and was mint for 550.00! Nice low grumble and after 8k it really comes alive. Only had to buy the exhaust servo eliminator and fender eliminater kit. The sound isn't annoying on long rides either. Just keep an eye out on e-bay for the best deals.

 

well i have looked around...i might wait and see if i can get a good deal on an arata or akra or even leo vince...also i was wondering the arata exhaust company says that when they did the dyno with a kit ecu they got 120ps!!!

i was wondering where to get a kit ecu or do they just take and modify the excisting ecu??? (Kawasaki KRT Kit ECU) i tried looking for one to buy but nothing comes up...if i get it i will increase alot of hp over stock...i was wondering if i try and get one of these would it be better to use the stock harness and just plug in...or should i rewire the entire bike for a krt kit ecu???

i could buy the map for $336 and get the exhaust really cheap on ebay around $1000..but i will have to wait for someone to post one

also is it easy to remove the db killer in this exhaust???
