While under the car yesterday i was able to confirm I have an axle back corsa exhaust (Quad black tips). I was initially thinking they only made catbacks, but I stand corrected.
So with this new knowledge, I get lost in searches for what, if anything, I should do next. With my axle back (which is nice and loud as-is), is it feasible or even worth it to add an X pipe? Would this equal a catback?

I'm maintaining warranty so am not interested in headers or tunes. What are the advantages of going X pipe if that is most logical next step?

Again searching "Corsa exhaust" is exactly exhausting so I wanted to get a few straight answers on my current situation.
