I of course know the difference in material but want to know the difference in performance between the two. is it worth the money getting the titanium. Also, does everyone recommend the full system over the regular. Does the header pipe add to the performance.

 

I'm sure someone out there knows the difference or at least can tell me how they like there particular model and how much gain they got from it

 

Yes header pipe adds performance.... Are you talking about comp v. TRS? TRS is suppose to be quieter because of tri-oval but w/o S/A it flows better. Ti v. Norm Ti is just going to save you weight nothing else
