Hy everybody, I'm JIM from France. I'll get my new bike next Friday it's a 07'/ 1584cc / Road King Custom / VIN: 5HD1FY4117Y706xxx / Stage1.
I've got some questions:
I'm not sure about the right model for my new bike, please could you confirm that the item 628-78055 will match without technical modification? this item is a slip-on model isn't it?
thanks in advance!

Yes to both questions.

thanks a lot, I ordered them this morning!
I'm going to read all topic on the technical area, now I need to know if the item 628-78055 comes with open or end cape and also know how many disc should I put on each exhaust to get the best result on my OEM 1584cc stage 1. My goal is to increase the torque more than the power, do you have any idea? thanks again!

The system comes with closed end caps and 12 discs per muffler. You may want to purchase an extra 6 pack of discs. Start tuning with 8-10 discs on the left and 12-14 on the right. Add to the right for more flow.
Keep in mind if you decide to go with 3" "open" end caps that they flow for 6 discs (6 discs+open end cap = 12 discs and a closed end cap.

Hi everyone, I just want a tell you that after 6000 kms with the item 628-78055 on my Road King i'm 100% happy.
As Bschultz said I put 10 and 14 discs and it' perfect: not too loud, good torque, looks great.
