its only to be used at weekends and the odd night out ... so i dont mind a bit more noise or a lot (lol) and would like to go the stright thru and de-cat route if poss... theres a nice blitz nur exhaust system on ebay right now which seems pretty good but they arent sure if it will fit a 94 wagon

 

Impreza exhaust systems, downpipe, centre section decat systems and de-cat, Afterburner, Ninja and Racebox : have a nice selection

 

i have a ninja system and its a very nice quality and loud ish exhaust. the blitz is suppost to be the daddy of loudness, do a youtube search to give you some idea, there are loads on there to listen to. as long as the exhaust is from a classic scooby it will fit oyur waggon
