Question-I've got a gutted OEM LGT up-pipe that I got off another member that he ran for a while. Do I need a reflash or tune to run this catless up-pipe? I just trying to protect turbo life,not gain hp.
On the oil issue-I've run Castrol Full synthetic/OEM Subaru oil filter and change it every 3k miles/4 months(more by months since I've put 3k miles this last year). I tossed the banjo bolt filter @ 77k miles and it was crystal clean.
