1999 Ford Festiva Muffler

I have a 1999 Ford Festiva Hatchback (1.5 litre). I want to install a muffler (sporty sound) but not spend too much money. I want a little sporty note to the sound but not extremely loud, ive looked at xforce,
universal and Redback. Also does size differ as per different hatchbacks?
Thanks in advance
