Yep, that's right Yamaha got together with TRD
to manufacture the head for the GTS. LC Engineering was in the mix too.
I hope you love the header, I am sure you will.
Lucky (Mike)and I were supposed to get a free header from DC, for all the hard work we did to get the dyno results for that header, so I am not to pleased with promises not being kept from them. Other then that it's a good header for the price.
