any good

Will i get any gains by fitting an n75j and 710 n to my 1.8TQ a4. (B5) It has filter, exhaust and chip. Where can i purchase these parts from, i guess they are genuine parts off a higher spec model, is this right? Has anyone the part numbers?
Want them fitted for the weekend!!!!!!!
Cheers

seen on here that if your chiped you should reverse the 710n
