Alright, so I received my stack and filter today. installed it and didn''t really feel any difference other than the intake got louder. plus my xd is an automatic so there's not much you will notice from it, but the rpm seems to climb faster, owell. It was a pretty tight fit because of the v-satck and the size of the filter. It was dark already and I used my phone to take pictures so sorry for the sh**ty pics.
