Just installed the headers with the black thermal coating myself today and it wasn’t too much of a pain in the ass like the spark plugs but i’m happy to say that’s another thing down on my mod list 😌. That one bolt on the overpipe next to the O2 sensor was a bitch to screw on tightly but it’s pretty much on there tight, the other bolt you can see maybe 3 threads that have passed through the bolt and the one close to the sensor you see maybe 2 threads..should i be worried? The header to overpipe connection is rock solid (with the gasket in the middle of course) and i checked every bolt that connects to the manifold 3-5 times before i put the skid plate back on. I read through forums and on here that after a good drive i should re torque all the screws (which i never used a torque wrench while installing tbh but i screwed them all on with a ratchet till i couldn’t possibly turn it more!) After installing and starting her up she was a bit louder than stock i just wish i made comparison videos to really tell the difference, also i got no CEL before tuning so that’s a good sign right? Later I tuned it with OFT to Stage 2+ and went up the street maybe 2 miles there and back. Not sure if that’s not much distance to hear the subie rumble but it’s drives better i definitely feel it, totally in love with it! (Completely unrelated: Would a catback open up the sound more? I have the Remark/FT86 Quad Exhaust with Burnt Tips and everything else on the exhaust is stock) also i live in Florida so i don’t have to worry about emissions
