Exhaust Nuts - GTO/3000GT This is M12 x 1.25mm with a 17mm Hex which is quite rare. This size hex allows you to use a normal socket on the front pipe to manifold studs making fitting the frontpipe a whole lot easier. Non Turbo Models use 4 of these on the frontpipe to exhaust manifolds & 2 of these on catalyst to middle section of the exhaust. Twin Turbo Models use 4 of these on the frontpipe to exhaust manifolds, 2 of these on Front Pipe to Bottom of Front Turbo Elbow & 2 of these on catalyst to middle section of the exhaust.
