ok ok, this is what i have done , i removed stock header pipe and exhaust and put jardines on, no cat box, it was removed with stock system.. that makes sense because i could not believe i would have missed something like that picture nolton posted i was kind of freaked

.when i put the jars on i had read a post in here the gaskets were copper. so i assumed they were in those ports in the head i mentioned. now i drag race old cars traditional v8s and i put copper gaskets on my headers so i can reuse several times. but when i remove and replace airplane exhaust we can reuse 1 time for the thick copper gaskets. so i figured i would try to get away with it on my bike , kind of a gray area in mechanics so some do some dont i might, because i have a slight tiny leak but i will retorque first and see what happens

thanks guys for the guidance i appreciate it..
