I personally chose the AWE track exhaust for my 21 STI. Got it from Subispeed and I don’t have a single complaint from either company. AWE just has that perfect balance between rumble and how loud it is. Cold starts can be on the louder side but quiets down quickly after a bit. AWE made my STI sound how it should of came from the factory. Im running a stock down pipe and driving around reminds me why I love my Subaru so much.

To me the MBRP sounds the best. I really like that sound and can hear it all day long.

I have the MBRP on my 2017 STI and all of my family member complain my car is too loud. Yes, that’s perfect 🤩. Pops and bang a lot. ❤

Got the AWE Track for my 15 WRX. ZERO complaints. Amazing sound

[JPnavarro]

I actually love my Nameless muffler delete full catback on my STI. I got the 3.5 burn tip. I fell in love. The Sound of the muffler delete sound fenomenal!

[livingstons]

I run the AWE track and it definitely has the deepest rumble tone out of most exhausts I’ve heard. Glad I went with AWE

[Not.The.Avg.Smitty]

Stick with my home build, no leaks, all vbands, purged pipe for proper welds, proper fitment, great sound and quad tips ftw!

[andybiscuits]

I’m glad to see AWE on the list and I’m so glad I chose them. On top of the fantastic sound, AWE has been a great company to do business with in my experience. I will def buy more products from them in the future

I got the AWE Touring Edition on my STI. It sounds amazing even when I drive it at normal speeds. No drone on the highway either. It's the way it should have come from the factory.

[Motoagogo]

Ended up running the Corsa Sport Black series on my 2019 STI, really happy with it.

[fifyfofum]

Gotta love the r400. I have it paired with a cobb intake and bpv. Definitely looking forward to add a j pipe to it

[NellysaintsSROP]

Invidia Gemini R400 has the most bass/ raspless you can get that doesn't sound like a straight pipe rasp but It gave me Tinnitus so be ready for drone extravaganza but It is the best looking quad exhaust out there with the thin-walled exhaust looks massive than a double wall even similar size.

[ALLANG]

Awesome seeing you and Kevin out at subie fest! Thanks for taking pics with me bro!

[holyjellyx]

I love my Cobb titanium cat-back, very mature sound.

[mrchsehed]

If I had an STI, Mbrp would be my go to.
I'd go with AWE for my WRX, but I do like the Tomei sound also. Just looks weird as a single when the rear bumper has dual exhaust outlets.

[Mr.Wongburger]

ELH, Cobb downpipe and Fujitsubo catback. Perfect.

[karlkincaid]

AWE fan boy here, lol. Had their stuff on my VA and now on my VB. I run Touring and it's perfect. I tried a bunch before making the switch. good. Great vid!

[devanlacroix]

I run the Cobb titanium on stg 3, 20' STI & it's middle of loud & quiet....exactly what i was looking for.

[JORGEGARCIA-uuzi]

There's nothing better than Japanese made exhaust systems, quality is superb.
