I just got a new 5zigen Jasma 4-2-1 Type r header with a 2.5" ID collector for my 98 gsr. Now I'll be needing to buy the right dounut gasket & flange for the 2.5" universal cat i plan to get next. So my question is will the Vibrant J-Spec header flange kit and dounut gasket kit work for this header? Or should i get something else? I saw Blox offers a 2.5" flange for a bit less but i doesn't look as nice and no gasket with it.
