R400 or Q300 (I know it must get asked a lot)
Hey all. After losing my 06 blob-eye a few years back, I've managed to get a really nice 2017 STI, bone stock.
I have a list of things I'm going to/want to do and on there is the turbo-back exhaust.
I'll start with the cat-back first to save me a tune for now, but I wanted to ask if anyone has the Q300 on an STI, and if it's more prominent than on the WRX. It seems just a little too quiet on the WRX, and I've heard that it sounds a bit better on the STI's.
I've been doing my research, and it seems like the R400 is golden, but can get a bit loud once you go the down-pipe as well.
If anyone has the Q300 or the R400 with the down-pipe, and can shed any light on the tone/volume (bonus points if you have it before the down-pipe and can share the noticeable difference) I would be most grateful.
I'll be getting a cold air, and the access-port too, and if I do get a valve it wont be a BOV.
