Ok, now I know i've posted about this before, but not only what is the difference between the yoshimura rs-3 comp and yosh trc pro series for the Z but also is it worth the extra 200 for the pro series? I'm really not sure I wana spend the extra 200 bucks for a Ti header and tri-oval canister, if it's a huge difference tho I will buy the pro series, anyone's thoughts if u have either system?

 

anyone?
