Just got a MY06 STI and want to know if this is the standard muffler fitted to this model. Nothing around here to compare it to unfortunately, no markings on it.

Looks like an X-Force.

Yeh but not chrome underneath, and inlet is only 2 1/2 inch.

Fyi its not the OEM muffler, would have had the "STi" logo engraved on the left side of the tip.
Could be anything if no branding on it.

Funny thing with it is the finish on the actual muffler, looks standard like. Next question is should i now just buy a new dump pipe and middle section to go with this muffler?

True.
