bro finding original stuff will be tuff.....but you can find piping around easily
if you cant find the complete setup then do the following
place an after market intake ..and move in unber bumper on place it by removing front head light....this will give you fresh cold air and will help alot
use an exhaust tip..and remove cat and middle exhaust ..and keep the stock piping
cuz if you used piping wihtout headers.above 2 inch..this may result in low back pressure....which may give you advantage over high end...bu will decrease your acceleration in first gear....
