TIP - use a 3'' long peice of wooden broom handle and wedge it where the D/V goes ,
Then pull out the the vacum hose that fits into the front of the D/V , Use a bolt to wedge into the end of the silicone vacum pipe if your not 100% confident in removing the pipe work completely , this will eliminate the D/V set up [ just Remember to tuck it away some where its not going to either melt on something hot , or get stuck/ wedged in.
Then remove air box and fittings , attache the 90degree bend to the turbo cold side , then place the metal pipe into the bend then filter at the end! . yeah maybe a t2 will sound slightly different but still miles better !
