i just wrote that because i see that a lot of guy on this forum a using the X6 big core. i have been told by the guy in the shop that is i was going to run an engine without big bore, cam and port, i would get better result with the regular core. And also does the regular core has a nice sound or the big core sounds way better. I just wanted to make sure that the guy who sold me the pipe wasn't bullshitting me ! thx :3question:
