Home addition plumbing wye into septic

[Jbartho5]

Upstate South Carolina

I wanted to ask opinions on this tie-in/wye set up. I am in the process of having an additon built on to the back of my house that has a full bathroom (shower, sink, toilet). The 3in drain pipe runs along the back of my house, turns the corner via two 45s and heads toward my current drain pipe as you can see it enter the photo from the left side where the orange plug is in for its current leak/pressure test. I wanted to ask about the amount of turns this set up takes as it connects into my current 4in drain pipe going from my house into my septic tank. Even though it has passed inspection, is this going to be a constant clogging problem? Also wanted to ask opinions on the use of steel banded couplers here vs using rigid PVC couplings?

Any information is greatly appreciated!

*As an aside, I will mention that at least the county inspector has already been by and said the current set up is good to go*
