I want mine to sound deeper and still remain loud. Anyone?

 

My friend cut his Yoshi about 3 inches and the sound and power were the same just looked different. Hope this helps

 

I have one I am gonna be selling soon

 

i have a d&d carbon pipe i cut down for my fighter ill go take a pic and put it on here for ya i can tell ya exactly how to do it as well

 

Unless you are going for a MOTO GP style or you are going to be doing 12 'o Clock wheelies than i wouldnt bother cutting down the pipe. D&D's are way to damn loud the way it is. They are more annoying than anything.
