why? is your origional one broken?

new powertubes do not increase preformance in any way. they only advantade they have it they are metal, therfore stronger. thats the only reason to replace it, but not for peformance reasons.

the gold powertube is the only one that is actually different in that it is completl flush on the inside and it ment for users who can adjust their velosity in other ways, like regulators and RVA's.

but, since you have an RVA, i would say if you ever had to replace your powertube, stick with the Red Hot Powertube.
