Exhaust Manifold to / Header

Great for High Performance engines, with Extractors or Turbo  Manifold.

Get rid of your original 14mm or 17mm bolts and huge spanner that  doesn't fit in the tight gaps of a performance manifold.

 With MAMBA High Tensile 3/8" Stud and 12 point Nut set, you can use  a nice compact 11mm spanner to do the job properly. No more leaky  manifolds to turbo joins, from where you can't get your spanner on,  no more busted knuckles and thrown tools! To make the job even  easier, we have an internal hex socket in the end, so you can fit  these with a hex key.
