I think ours is 2.25" stock. Maybe 2". GS-T is like 2.5" or 2.75"
pretty sure it's like NT-2.25" and T-2.75"

I just got new piping, and stock NT's have 2. I'm not sure about T's I pretty sure there 2.5

It should be 2.25" outside diameter, or 2" inside diameter. It's the same size piping for NT's and GS-T's, except the GS-T's have an extra resonator and higher flowing muffler.

nt's and gs-t's have a 2" catback. gs-t's have better flowing muffler.

I figured gst's had like 2.5. Seems weird that they have 70 more HP and the same exhaust basically.

Might be that whole turbo thing Haha, just messin'.
