    Night Sticks?HD super traps exhaust

    Night Sticks?HD super traps exhaust, If you were ever interested in what they look like inside , here it is. I had wanted to play wit adding a couple disk.
    Stock is 10 disks in the 2 pipe system I added 2 more to each. As is common I ran into issue. The disk bolts did not come out well on one side so I did have to do a little extra work to get the side done. Adding 2 disk I did not need longer bolts. If you want to save a few bucks just go buy SS bolts with allen or torx head the length you want in a 10-24 thread. I am assuming two disk will not make a big change in flow or tune ,I will run a new auto tune soon.

    No the exhaust comes right down the center it then hits the disk. The number of disk determines how much flow to get.
    The more you add the freer it flows. I have heard of some adding 10 or more disk.
    On the Fatshotz style they have a plug in the end when the plug is out the hole is smaller and restricts flow and you tune the disk the same way. On the 2 to one version they plug the hole.
    The night sticks have a closed end

    On the ride to Oshkosh last night wife said it was a little bit louder deeper tone when rolling on the throttle. I did not expect adding two disk to be much of a change. Leavening for Chicago with it today and will run a new auto tune on it.
    Who knows I may add a couple more.
