I had a full turbo back decat Zero/Sports system on my last forester sti! I loved it (at first ) but like you, the rest of the estate was woken up when i went to work and the misses refused to drive it anywhere because she was embarrised (bad spelling) by all the dirty looks! so the novilty wore off so i put the origonal back on, with the decat though!!!
Have full millteck 3" with sports cat and she's not to loud at all ( a bit boomy if you reverse right up to the front porch door) but other wise perfect!
Best of look with yours!

i'd be arrested if i drove into a multi story carpark, i can only imagine the noise it would create, but im actually getting quite used to it now, pity the neighbours are'nt though
