Cooper S 2002 Mufflers

[Farmboy]

Really need help!

One of my mufflers recently cracked and would like to replace both. I was informed that magnaflow is the best option, however, they only have the cat back system which is the full exhaust system. I don't think this is necessary but if its the only option then I have to do it. Are there individual mufflers that I can get for each side and if there are, what brand should i get? Part no. or dimensions will be a great help as well.

Thanks in advance
