I really need to take my car in for the checkup from Subaru.. but I'm really afraid about takin it to the dealer. I took my car in a few months ago for a dead clutch and I had a BOV/cat-back on.. and they still did the work. Now I'm catless with a turbo.. that's basically all they will see. Do you think they would void the warranty? What is all of your experiences with this?
