How do you have a shop built catback if you have a stock midpipe? You're just looking to change the axleback.

It will probably be just a little bit louder than what you have already.

Then don't you have a bottleneck at the cat?

not very loud.

I use a cherry bomb glasspack as an axleback when i race, so i can hear the motor under a helmet, and in retrospect i should have just made a straight pipe. All the other crap in the system quiets the car way down.

I've got an N1 on my Bugeye Wagon with a Cobb catted DP and straight thru mid-section (modified, but from an STi) and it's loud. Granted, you have a stock mid so yours will probably not be as throaty but it will be loud compared to anything stock. I get a lot of drone inside, but there is no resonator so that's somewhat to be expected. I love the sound though, everyone can tell it's a boxer.

Turbo and N/A exhausts are quite different in terms of volume/change. An N/A exhaust is always going to be louder with the "same" changes because the turbo will absorb a lot of energy from the exhaust. Sound being a big part of that energy.

The stock cat (cats on some MY's) really does quiet the exhaust down a lot. With stock cats and any kind of muffler, it wont be crazy loud.
