Stainless or Carbon Fiber?

[Crazy]

I'm thinking about the Yoshimura TRS slip on, either in stainless, or carbon fiber.
stainless is $305 and CF is $410.

any opinions one way or another? or recommendations for other exhausts?
probably going to order today or tomorrow, hopefully will get home by 4th of july... but i might put it off until mid august when i get back home for good.

planned mods/ stuff to buy, all cosmetic/ poser mods :
- flushmounts
- rear seat cowl
- cut the shovel of a fender off
- Yosh TRS exhaust
- frame sliders
- new upper fairing (current is cracked from lowside)
