Hey all, I'm sure this question has been posted before, but I'm still a newbie at this. How do you tell the 6X-4 from the 6X-8? What casting numbers do I look for?
I have a set of 4X right now and it's cast on the center exhaust ports. Is this the same for 6X? Will it say 6X-4 or 6X-8?
Thanks for your time, you guys are always a wealth of info.
