loudness difference between 10" and 17" cans?

Does anyone on here know how different (quieter/deeper) 17" cans of the same design would be vs. 10" cans? (same diameter, packing, etc.).

I'm getting the last of my design for the exhaust together, and mulling over different lengths, and most likely I"m going to go with the longest I can get (17" or so), and angle those up & in like a lot of the mid-late 90s and early 00's bikes did.

 

10" can are nosy

 

Never heard of over curious cans before ?

 

I have a short D&D on my bike it growls beautifully but she is also LOUD
I personally LOVE the tone

 

After some poking, I've realized that my supertrapps only have about 9-10" of core in them, and then it switches over to the exit baffles. Which would explain a lot of my dissatisfaction with the loudness. Right now, I'm looking for some numbers, as I've only been getting vague statements from mfrs (which is rather annoying).

 

Longer is better, the sound can still be good, but the volume will be a bit less. No sense annoying everyone. And louder won't make it go any faster.

 

Try getting 8" open mini carbon cans

 

That's basically where I'm headed with this.
