I got a bunch of 5zigen **** for a gsr and was wondering what all they make. I kinda want to stick with all the same company. I have there springs, exhaust, header and oil cap. Anything more that anyone has used? Really happy with all there **** so far. The header was "race" (in turn being longer so i had to make a test pipe that would fit), but damn does it pull.

 

why do you want to have all 5zigen parts? there are better parts out there.
