[996] Is this orgiginal or sportsystem?

[HolmaN]

Found this for sale, for a 996 3.4 / 3.6.
Is this original or stainless sport system?
My eyes can't tell...


On another note:
I'm interested in getting a better exhaust sound from my 996 -98 with a low budget.
Is it worth it to only replace the mufflers to stainless or is it a waste of money?
Shoul I rather save for a proper full exhaust system, or is it worth it to go with just replacing the mufflers?

Thanks in advice!
With kind regards, Jonathan.
