standard chinese shit... DO NOT BUY
a turbo charged car does not have the "extractors" that a naturally aspirated car has, on an NA car, you have the head, the extracters/headers(on a 4banger they are 4-2-1 or 4-1) then the rest of the exhaust.
on a turbo car you have the exhaust manifold hanging off of the head, with the turbo on that, then from the exhaust of the turbo- the first bit is called the dump or down pipe, then from there too the cat is the "front" pipe, then your cat, then the catback system which ideally has a midmuffler then the rear muffler
