Super Trap Disks ratio Question
If you are using the Super Traps what are your disc ration and why.
Also, it would be helpful if you could indicate whether you have a PC and Stage 1 on your scoot.
2007 Ultra Classic, I am trying to see how many I can put in to increase the sound without losing much in power etc.

Not being critical here but a proof read and spell check (ration?, Simper FI?) will go a long way toward someone else understanding your question.
Super Trapp's are a very good but they're not widely used them so you might be on your own with this one.

18. 20 was a little louder without any real top end improvement. 16 felt good down low and was even quieter but sluggish above 3500 rpm. I used even numbers for no rational reason. Your butt dyno results my vary. If you want sound you can always pull the end cap, or get a set of Rineharts.

Modee, a search will show a ton of posts on this subject. A lot of hdforum members use them. I reviewed these after a search in the past and based on similar builds to mine I use a "ration" of 9 with the open end cap and 16 with the closed end cap. And great torque curves on my dyno runs from Lees Cycle tuning using the open end cap, although other tuners have reported issues optimizing dyno tuning when using the open end cap.

Do you have the 2 into 1 or the slipons? I have the slip-ons and have 17 in each side with the closed end caps. It a little quieter than other exhausts and I get goos low end torque and fuel mileage.
