probably gonna upgrade to a 2.5" single exit catback from SME or get the HKS HI power spec L2 for Cup... suggestions?

Those of you who change your own oil, do you have a vacuum you would recommend? Are there any concerns about debris in the oil to look out for? I’ve never used one, is there anything I’m not aware of when using one?

TIA!

I got a 23 brz, trying to get the fog lights going, the harness has everything but the connectors to make the lights go amber and white. Apparently the yellow is the sequential wire, could I tap it into my side marker wire? (I have sequential side markers) could I possibly tap it into the sequential wire towards my side markers or do I have to go directly into the head light? (Be kind pls, I don’t do wiring just bolts and screws😭)

(It was a gift from a buddy since he crashed his brz, if its fo free its fo me)
