I bought the E kit from rpmoutlet, I am very happy with it don't get the 8lb lower pulley though it was to much for mine should have done some research before I bought it took it off and put the cog instead
Oh boy another discussion on my cog, I get zero belt slip yes it is very expensive and probably not worth the money, but we were comparing how quickly my boost comes in compared to another L with a pullie and mine was alot quicker. Also the sound of it is awesome here is a link for a vid of it
