R34 Gtt Exhaust Questions

[Haxorz]

I'm looking at an R34 GTT for sale.

Here is a photo of it's exhaust.

This is a Nizmo factory option, right? I've been on Prestiges list long enough to learn most of the factory options and am pretty sure it is. It also has that interior 'Sports / Silent' switch in the cabin under the steering wheel to the right.

My current R33 has a custom 3" from turbo to cat then a HKS 3.5" cat back + an Apexi air pod and has 160rwkw. This R34 didn't seem to go as hard (it just has this exhaust, no pod or other power mods), but maybe cause it was newer and smoother? Dunno. Thought it was strange though cause the R34 supposed to have a few extra KW's over an R33. Anyway, my questions:

- Can anyone tell what size this exhaust is? 2.5"? 3"?

- Does anyone know anything more about this spec of exhaust?

- The dump/front pipe is still the standard (restrictive one) right?

- Is it worth replacing with a 3 or 3.5" exhaust?

- Is there a big power difference between 'silent' and 'sports'?

- Dummy question here - will an R33 cat back system fit an R34?
