Thanks yall, question is now resonator size and what not, i know im going with a vibrant resonator but dont know if i want ultra quiet or bottle style resonator?? sound is important to me I want a nice tone that is somewhat loud but not drone or rasp. I was thinking Large Diameter Bottle Style Resonator, 3" inlet/outlet x 18" long.

I can't guess about the sound of that resonator, but be considerate of chassis and ground clearance. The OEM part is the size and shape it is for a reason - not much room down there.
