i disagree DS. the yosh full out performs with mapping most, if not all slip-ons above like 7000 rpms on a street bike FWIW

most aftermarket fulls measured the OEM honda headers and have the same length primes and the same off the head tapers, all of them in fact

I also have the capability to make 60mm fulls with HRC collars i bought for the heads stephen
