I was lucky here, my sound was diabled prior to initial collection and I'd anounced before we got home adn stopped for lunch that I will need an exhaust.
After much umming and ahhing I ordered the Apex'i and commented I'd gone for the sensible quieter one, she said "if you are spending money on noise get the louder one", so I cancelled and ordered the HKS instead.

Swizzle was that your OEM filter? - it looks like the Mann one with teh built in activated carbon. Mine was a rubbish paper affair, I upgraded to one like yours.
