Hi I am new here as I have just purchased an 2002 STI Prodrive which I collect on Saturday. The car I have bought does not have the PPP fitted. The dealership said it's got the prodrive exhaust with some of the CAT taken out, a modification done by the dealer and said it would have about 280BHP. How can I go about getting it to the same power as the PPP 305BHP without paying out for an entire PPP kit @ £1800?

TIA

Nick
