Catback with intention to go Stage 2 advice needed

Hi, new to the forum and apologies in advance for being a novice...

I have a 2017 WRX 6MT and am looking to start with just a catback exhaust and eventually do a stage 2 (can't bring myself to kill my warranty just yet). It's my daily driver and I'm not trying to make it too loud but I def want a deeper tone and little more aggressive.
Looking for recommendations on catback exhausts and then a J-pipe that will work well with a standard Cobb map- basically trying to avoid a proTune if I can but don't want to add unnecessary risk to engine if parts not mesh well with the standard maps.

I like the sound of Invidia Q300 or the Subispeed Quad Tip Catback- thoughts on those?
I wasn't overwhelmed by the Cobb catback but I imagine going Cobb catback and eventually cobb J-pipe when I get the accessport would be the safest way to go.

Anyone have good success with non-cobb aftermarket parts when they went stage 2 without a ProTune?

Thanks!

Although you are free to take whatever action you see fit, I would STRONGLY recommend to meet up with local Subaru owners and take a drive in cars with specific exhausts. Sound "quality" is a personal preference and YouTube videos rarely sound like the actual exhaust.
Hey, I actually really do like Agency Power's setup.
Listen to it in here.

This is a Stage 2 with a catless DP and an ELH upgrade.

ProTune is not something to 'avoid'. Actually, way better option compared to an AOS tune.

I suggest you to go with a turboback system with a high-flow catted DP.
The ELH upgrade would also be quite beneficial for the sound and performance.
Wait til at least 10K milles on the car then go full Exhaust, Jpipe and Intake. Its like driving a whole new car. Enjoy!

This. You really need to hear the exhaust in person, preferably on a short drive in the cabin to really make an educated decision. Assuming you don't look/smell homeless, a lot of people would be fine with taking you around for a few blocks to let you hear the exhaust.

2015+ WRXs already are EL manifold
Here's an example of someone who bought before listening. I had the Agency Power Catback but never got to install it because well honestly the fitment sucked and the welds looked like a squirrel got to them.
For 750 you get what you pay for right?

Then I bought and installed the Invidia Q300 quad tip, wasn't that bad but on the highway cruising around 70-75mph the drone was pretty obnoxious for my taste. I ended up selling it to a friend at a small loss.

Like the guys here say, go to a meet or something. I went to WRX vs EVO day at Raceway park in NJ and heard a ton of different exhausts. Fell in love with the Corsa catback. I also picked up the catted TurboXS J and Mid Pipe too. Ah ?

you're on the right track with the Cobb catted TBE, and an access port, I've heard Cobb's TBE and it's delicious, but for the money if drone isn't a big deal get the q300 or even the R400 exhaust. Stay away from cheap pipes. No SUS garbage either.

I wish Corsa made a catback for the 02-07 WRX/STi. I'd buy one in a heartbeat...
Corsa is a fantastic catback.

I'm also a big fan of ETS.

Good luck with your build!!
I've got the COBB turbo back and couldn't be happier. I think it's a more mature sounding exhaust that still gets you noticed.
i've heard nameless is really good. Thats probably what i'll end up getting soon here.
