PIPES- what's the size difference ?

Hey, I'm just looking for a set of new pipes for the SD, I've found the sellers quoting different blocks of year models for their pipes to fit.
Some saying these pipes fit '06 to '09 , others saying '07 to '10.
So is there a difference in size of the ball socket joint ?, if so, what year did it change ?

I like the look of the Yoshimura RS-3c, does anyone know if there's much of a weight difference between the carbon and titanium models ?

As far as I know they are all the same but i'm sure if I'm wrong someone on here will know.

Looks like you must be right then oafboy, thanks

yep all the same jace

Groovin', I've found a set of yoshis for $735 posted. That's as good as I've seen for quality pipes.
