Yes mate thats the one, It came with a reducer and went straight on my standard system. Was close length with though but its on and doesn't blow, It certainly felt like it went a little better although i had R-Tech map it at the weekend and with only a pipercross panel filter it made 151 Bhp before and 185 and 220Ftlb After, There was a guy off here who went before with no De-cat but K&N 57i plus milltek (No De-cat) Who made 157 before and 195 after. Id say the full system is definatley a worthwhile buy.
