I realistically won’t get in to engine mods until the end of the warranty. Especially considering the rims are coming in at $1800, plus tires... So just the financial end and how much my wife will put up with me spending on the car consecutively will push me out, considering the down payment and tint and the few little extras. Plus she’s gonna need a car next year. I do have those wants though. So, eventually. 💪🏼There isn't a better blow off valve than the factory bypass valve.
A new car I would stick to non performance mods. Things for comfort or looks. Subaru is notoriously stringent about what they will warranty. Modify that part and you can write warranty work off. Engines are expensive. Real expensive.
