If you buy your drive kit from B&C Express they will send you the 2 sprockets in the standard sizes i.e. no alteration from 15/46 unless you ask them for a different gearing and a chain which is the correct number of links. However the chain comes splitted and you will have to borrow a chain tool to lock the pin back and I tell you it is a very hard fit.
The quality of the items sold by B&C Express is superb, these people are the most professional in the field, they can take your phone order and when you talk to them they will advise you on the best quality vs price available for you.
I have been using them for 3 times in a row now in the last 3 years, the kit I have bought from them is called 4172 RE.APX which consists of the following:
The sprockets are both Renthals, you get a stiffened aluminium anodized rear sprocket and a steel front one their chains are Tsubaky X-ring and never had any problems. They last twice as long as the OEM by the way.

However I have just ordered a new set myself and this time I have asked them that I want to experiment with an even longer lasting and stronger set, even at the expense of little bit of weight or cash and they have sold me their top of the range rear sporcket which is a Renthal Gold extra strong and a Renthal Y-ring chain, the price came to �114 all in, which is an extra �24 but if they do what they claim i.e. last even longer than their other set, then it's got to be a deal.
Give them a call see what they suggest. A lot of us have used them and are very satisifed with their services.
