Its a NRG carbon fiber shift knob. Yeah got a free set of 350z seats when i was workin at Forged and i didnt have a driver seat so lucky me. Same with the Greddy can. Its from the driver side of a Z and then i welded alll the exhaust for it to fit on. Exhaust is all 3 inch stainless, no cat or resonators. I do plan on pullin it all out again and starting to build it once my del sol project is done too.
