ok, so i'm trying to understand the difference in the amount difference between test pipes, but i just can't seem to justify it. i understand resonated will be more then the non res ones. what i can't understand why is top speed $150 brand new, invidia $200 brand new, z1 $270 brand new, and so on.

if they all do the same thing, why such a difference in price? i'd understand if it was a few dollars difference.

can anyone shed any bit of light on this???? it's driving me crazy
