Coated exhaust

[Blown 331]

Well I've decided to go with a Sparks pipe for my 450R. But I'm not sure if I should get coated or stainless. I've heard the ceramic coated can rust so I guess the head pipe is steel? On the stainless system is the whole things stainless?
I don't want a pipe that will rust. I had a White Brothers full system on my 400EX and it was all stainless or alluminum. There were no parts that could rust. I'm looking for the same thing, low maint. Does anyone know if there are any parts that can rust on a Sparks stainless system? What about getting the stainless system coated?

Just go for the stainless and use some polish from time to time and it should stay looking new.I have the white brothers full system om my 400EX and stainless head pipe and it still looks like new.
