hiya i got me self a ribbed pipe and man they look cheap even they are £32 .bit hollow, i thought they had atleast something in them or is mine something missing.
no my friend the ribbed pipe is pretty much just a tube.. lol i ran the ribbed on my savage x and believe it or not it ran pretty good with it and it definately has a unique sound, "almost a popping,crackiling sound" but i've read sooo many times that the hpi polished is a better choice as its quieter and apparently makes it snappier of the line so thats whats on mine now but haven't ran it yet!! but for the price its honestly not that bad of a pipe!!!!
