Max redline then some

So, new to WRX and subaru, I'm still learning and searching the forums, but haven't found what I'm looking for.
I bought a 2011 WRX, mostly unmolested. Doesn't look like any bolts have been removed or previous tampering under the hood.

It has invidia catback pipe but Borla mufflers, don't get me wrong sounds great...but I can't find the same combination anywhere online for sale. Thoughts?

Second it pulls HARD from 2k until 7K+ RPM then hits the rev limiter(i try to pay attn and listen but it just seems to want to go and go). And boost peaks at ~16psi then back to ~14, I haven't pulled the logs for it to see specifically where it sits.

I don't have a Cobb Ap, I'm just monitoring with Torque pro. The more time goes on I'm thinking it was tuned with AP, but not 100% since I don't have a good baseline.
TIA-Jorge

I'm pretty sure stock boost is 14 psi, you shouldn't be pulling from 2k rpm, ever. A cat back would be just a mid pipe and axle back. If the invidia part is attached to the turbo it's a turbo back and it needs tuned. It may also explain the boost issue and will also require tuning
If you don't have an accessport, I wouldn't trust that the ECU has been reflashed at all...

Gotcha, getting the AP is on my to-do list.

When I looked under the car it still had the "subaru" DP.

How do you know the mid pipe? I didn't think they labeled it and they are all generically the same 3" section

Forgive my ignorance, you're getting at the pipe from the turbo with the cat going down to the rest of the exhaust has the o2 sensors(pre and post). It looks stock, but I'll take a Pic tomorrow, you all would know better than I.
