FMF Power Core 4-2 and x-4 head pipe

[Red00Honda400EX]

Will the FMF power core 4-2 hook up to the X-4 head pipe without a problem? I don't see why not but I figure maybe someone will know for sure. Reason being is the dunes around here check for spark arrestors and well my Sparks exhaust isn't arrested :D and I'm supposed to leave this weekend for the dunes.

Thanks in advance,
Justin ;)
