ok so, my friend and I are trying to make a custom HP cag pipe....

^^Demo Photo^^
I was wondering how should we make it
big or thin?
and would we have it go over the spark plug (like a fat boy?)
or around the cyclender(like a jet pro)
I dont know if this is possible, but worth the try

.
open to suggestions...
btw
we are trying to put it on a Half Fairing cag
