@@alittleofeverything2869 just did my one, went full ISR and just waiting for the long headers, it was true, easy as hell to install and perfect fitment
Isr is for a deeper sound and not too raspy. You’re going to love it. But if it’s for FBO for the future maybe z1 better since I see it doesn’t have any restriction it’s just straight pipes
@@alittleofeverything2869 cool thank you so much! I wanted the isr y pipe but I think I’ll just go with the Z1 y pipe I appreciate the response thank you
