I don't know why I've only just jumped on this bandwagon but I was bored on the weekend and fancied a tinker, enjoying it so far, had to put jubilee clip on it and tie clipped the end so it doesn't flap around too much, haven't done too many miles yet.
Initial impressions, I love it but can see why some people got tired of it quick and swapped it back, I need to get a video, mine's not too loud but there's a really satisfying brief burble most noticeable in 2nd/3rd gear at low speed when the turbo hasn't spooled I love it.
Not sure i've noticed a difference on the road yet and the weather has been cold but consistently hitting 197/8 g/s whereas before on the std airbox and filter it was 187/189, maybe 192 on a good day. also noticed my maf is the oe one from 2002, just went over 90k miles the other day.
