well dear it depand on yr pipe size
few days back i did my khybeer piping with 1.75 inch compete for 2200 rupees
so a good piping for yr car will be 2.25inch piping...that should cast between 3000-3500 rupees
but many ppl will ask u more then 5000 or even will ask 6000 for piping....
but do remind u...yr car pick will be reduced...only u will have high end advantage
if u need pick as well...u have to get custom headers for yr car as well...without that...its just having stupid noise knocking yr head every time u drive
