Received my harvey smith uppipe today it looks very good quality, much stronger than the sti uppipe i had first planned to use just got 2 questions, will ask here first as harvey is not well at the moment and i do not want to bother him

1. the new uppipe has a space for a sensor on it but the standard sti one does not. will my wrx have a sensor to go in there or will i need to find a bolt to block it off.

2. the bolts on the flange do not line u exactly with the turbo's bolt holes it it pos to drill /file a bit out the turbo bolt holes to make it fit as it is only out a fraction maybe 1mm ?
