The only four-seater aerobatic aircraft I know of is the Fuji FA-200. But I think it's limited to 2 POB when flying aerobatics. And it's got a yoke instead of a stick.
All other combination tourer/basic aerobatics aircraft that I know of are two-seaters. For instance the Robin/Alpha R2160, Decathlon, General Avia F.22, Cessna 152 Aerobat (ahem - "Anemic" would be a more suitable term).
Further up the aerobatics scale, but down the touring scale, is for instance the Cap-10. And then you get the proper aerobatics aircraft, which are increasingly less suitable for leisure touring. Pitts, Extra-300 and so forth.
