    Im going completely cat less on my car (17’ STI) and open source tune of course but I’m worried about boost creep, especially since I live in a place where the weather and climate is so bi polar.

  2. 2.5 Liter/Litre Factory Motor
    I was driving home today and smelled an odd smell then when I was at a red light I noticed white smoke coming out of my hood.

    I have a 2015 STi base (non HK) and I would really like CarPlay but want to retain a more OEM look. How difficult would it be to swap in a HU from a 2019 STi? Are there any good guides out there? Thanks y'all!

    Wanted to share since this helped me out a ton. My car is right at 6000 miles. Making this post a little --verbose for others searching in the future. My symptoms have been around for a couple thousand miles now and just kinda showed up over time. I guess maybe break in...(?) IDK. But...

    Located in central North Carolina (Raleigh). I would prefer to sell the below parts as a bundle, but I'll split them out if needed. The bundle price for all of the below is $325 (not including shipping). These parts when new cost approximately $530~ (not including tax). These were used on a...
  8. 2.5 Liter/Litre Factory Motor
    Anyone running the id1050x injectors or similar along with a better fuel pump on a 2015+ sti WITH stock rails/lines. I need to upgrade fueling system but the lines and rails are spendy. I just have a turbo back exhaust, catless, and a cobb sf intake. I'm getting protuned via e-tune rn. I'm just...
