You're going to hear a lot of drivetrain noise with your STI. It's normal. I love it.This reminds me of a question I have been meaning to ask. The 17 wrx & the 16 sti I have are my 1st 2 subaru's as well as my 1st performance & turbo cars. I have always been somewhat sensitive to my cars sounds. The wrx made lots of "exciting" sounds, like all the whooshing when under boost, as well as some less desirable sounds like the click clack under the hood. The sti makes way more noise & I can't figure out what is meant to happen or what could be possibly wrong.
My sti was a certified pre owned so it was checked by the dealership & I paid a mechanic to look at it just out of paranoia , both said it checked out. I still kind of want to get it checked by a performance shop just to be sure but currently lack time.
One of the sounds I have been curious about happens every day I work. As I get off the highway I rev match/ds into 5th just before I exit then rm/ds into 4th to drop from 60 to 40. Durring this time there is a sound that could be described as grinding but it is not picked up well on my phone mic. In my head I can picture this as the sound of gears both moving together but not having consistent force on each other creating a kind of chatter. I also can hear my trans while accelerating and at some points while driving. Normal or not?
Overall the car just sounds more mechanical & everything makes noise. The brakes squeak a bit, the tires/ suspension augment road sounds, engine & exhaust. Its way different than an average car but what is ok & what is not? I feel like a lot of these sounds are things carmakers work to hide & I traded polish for performance. Its hard being new to this type of car because these sounds can be hard to pick up & if they are normal they wouldn't come through easily in vids online. Also, being subtle, its hard to "point" them out.
Sorry if I was off topic
