haha its not a copy! guaranteed.
do you know that there are four different styles of muffler from j's for the GD3?
actually there are two different styles, just two color variants for each.
the 50RS and the 50RR. ive seen the so called "fake" muffler at N1 concepts, and i bought mine from aj racing. now, why would the two largest j's racing distributors in north america simultaneously start selling fake mufflers? hmmm
