ok so i read all pages and i see that the 9886 is good for gt on novas
as i tried a 9901 and 086 on the 21-7 fms and it runs strong
what other pipe is good for 35 plus 21 or 21-7t/21-7r7/kappo/rally ?
and what about the os xz-r? what pipe are people running on this?
i have 2050,2060. maybe 2090? or a 2070 with what header?
