    Default HD SE Fatshot slip ons need Part #s for Closed caps

    I have the SE fatshot slip ons installed behind true duals on an 04 ultra classic, they have the stock open end caps and are still to loud on long hauls. I want to go to a closed end cap and extra disc. How many disc extra on each side to replace the open end cap and I need the part numbers to the closed end cap, disc and longer bolts. Thanks for your help.

    The 4" open end cap flows for about 10-12 discs. If your motor is tuned to the existing configuration and is running fine, I would suggest the "FatShotz" tune kit which is also the most cost effective; P/N 404-7881. The kit provides you with 10 discs, 2 closed end caps, two sets (6pk) of 2" screws, security hex head wrench, anti-seize and instructions.
    End caps, screws & discs can also be purchased by individual P/N's at our "store" at the website;
    P/N 404-7206...6 pack of screws (1-20 discs)
    P/N 406-3046...4" closed end cap
    P/N 404-6506...6 pack 4" discs
    P/n 404-6512...12 pack 4" discs

    Received the closed end caps and disc, the SE Fat shots now sport 15 disc each and closed end caps. The bike it noticably quieter with a nice deep growl. No longer has that obnoxious crack. I did notice a significant reduction in vibration and quite a bit better throttle response and a noticable increase in pulling power right off idle. I took a guess and hit it dead on.
