My Legacy Wagon GT-b etune was imported from Japan I brought it from a dealersip and it has an Sti badge on the back? it has a STI Genome exhaust and STI Swaybar. Is this just STI tuned/ add ons or something else?

Also does the 2000 Gtb etune wagon have any problems to be cautious about at th 170,000 km mark just had cambelt done....
