What kind of budget are you looking at? Long tubes, midpipe, catback will set you back a solid $1200 if you buy all new.add on installation...this can get fairly expensive.
You could just get manifold replacements for cheap ($50 each) or shorty headers for $400 and call it day.
Are you wanting loud? fairly quiet? Do you have to pass emissions?
