Was unaware that gauge face was removable till this exact moment.

Hi I’m just here to show off my fully built Subaru VA STI I spent 2.5 years building and man is she violent. Thought I’d share. Thx toodaloos!

My Blob.

Got this jpipe for the low. Doesn’t have and logos welds saying it’s brand. Any guess what jpipe would be? Maybe eBay jpipe, knock off jpipe or what. I just need to know because I need the V band clamp as it didn’t come with it when I got it.

Thanks

Posted end of 2025 but video clip wasn’t long enough. Old post here https://www.reddit.com/r/WRX\_STI/s/Kkvv0Pjl5E

I check the timing which was fine.
When I I ran a test start I could hear some sort of clunk sound then the car idle fine and slowly started making this sounds again.

Any ideas.

Thanks all

super easy install. dont need to take off bumper, just needed some plastic pry tools. stickers bought separately 🙂‍↕️

surely this improves gas mileage right??

the past 2 weeks I have been deciding if i wanna sell my STI, its got a jdm short block with 78k miles but chasis n trans is 156k miles. Its on a safe tune atm and has a bigger turbo but I want something to daily without having to worry about if it will turn on in the mornings. I really do enjoy the car and i have worked so hard for it, idk if i wanna keep it and invest in maintenance mods to make it somewhat more daily drivable or sell it and buy another car. I was looking at more Lexus is350 F-Sports or a Toyota GR86. I will say i want to own a performance shop in the future and i bought this sti to learn on how to work on subis, I have had hondas my whole life and i want a platform thats different.

Changed oil at 25k. Found this non-metallic piece in my oil. It's really small. Normal? Anything else to check or do?

Anybody wanna diagnose this chirpy rattle on 2015 WRX when revving without clutch engaged? ~68k miles, new clutch build last year

Buying my first STI. Dealer says it’s stock, but I think it has an intake. Can anyone help me figure out if it’s been modified? [if anyone is interested in collaborating on a sticky-able post to help buyers lmk]

I’m planning on getting an e tune from drunkmann and want to make sure I tell him all the mods that are done to the car. I bought the car used and I know it has the mishimoto intake and boomba bov. Is there anything else done I should tell him?

working on the STi after getting put in a ditch in december, one of the problems the car now suffers from is a leaky brake line, looks like it’ll be a pita to fix, you guys know what i should be looking up to find a replacement/fix for this? thank you. (rear passenger side by the fuel tank, 08’ sti hatch, bottom most line as shown in second photo)

The car is a bone stock 2010 STI Special Edition.

The sound seems to appear when holding throttle between 3500-4500 RPM.

If I accelerate through those RPM it doesn’t seem to really happen.

It sounds as if the rattle is coming from the vent to the left of the steering wheel.

I’ve dismantled the dash and tightened everything up.

I’m hoping someone may have had a similar issue or has any ideas.

Any thoughts where this oil leak is coming from? Highest point on top of the engine passenger side. I replaced the PCV valve and hose assembly. There is an oil galley plug near by that doesn’t have a washer or gasket if normal. I thought it could be the breather hose underneath throttle body but no UV dye from the oil around it. I’m guessing I don’t have the vertical PCV hose to engine seated and tightened correctly. Anything else from this area that can cause oil to pool up on top of the engine?

Hello everyone,

I've been wanting to change my exhaust tip with a quad tip but not sure if it will affect the car, I just want to change tip nothing else. The mechanic I took my car to said that as long as I don't do anything to from the cat to the back it should be fine. Any recommendations or insight will help a lot, thanks!

Just recently got 60k mile service, all new tires (Michelin Pilot Sport 4S), and aligned. Ready for summer.

I just found this 2021 STI Limited at 36k miles at the used dealership near me. I am not really knowledgeable about it as I checked and it seems stock but I want to hear y’all opinions. The boost is at 18.2 PSI as far as I can tell. Is it a stock motor? Thanks for the opinions!
