Copy paste of my initial impressions from December 23.
AWE Touring on my BRZ 2023. Shipping through vip-motorsport.co.uk, ordered 25th Oct, delivered 13th December, installed yesterday.
It's loud. It's loud, this is something I'll put on the first spot while describing the exhaust. While stock is quiet and muffled and cabin speaker starts pumping noise around 3,500 RPM, this exhaust is "talking" from as low as 2000 RPM. It's a mild "bassy", deeply tone. The best I would describe it - imagine small soft turbo stage 1 car - like a VW TFSI 2.0 engine or similar, noise level is comparable.
Sounds it produces inside the cabin are amazing! Finally some "Subie rumble"! You definitely need to be committed to pull a trigger on how much noise you want in the car, but if this is what you are after, it's definitely top notch.
Then into outside noise, oh gosh.... it sounds like a WRC rally car!

It's amazing as well, no "throaty" crisp and metallic noise, just a "meaty", "bassy", deep sounds and nice tones of the boxer engine. Downshifts from distance are phenomenal, you can easily hear the gas during the downshifts, it's awesome.
Pops and bangs - they are present but not obnoxious present, especially inside the cabin, moreover, you need to work on them to make them happen. They don't make a series of AK47 pew pews but rather 2-3 pops and that's all. It's nowhere near how some people makes tunes for pops-n-bangs.
Cruising at 45km/h on 4th gear (it's below 2000 RPM I believe) makes no sound at all.
Highly recommend if anyone wants to make this car more vivid as I fell in love for the second time
