 Exhaust Templates are available in our Tools Section. They come with the actual port shape scribed on them. You have to cut/grind the port into the template, following the scribed lines. |
|
 These are two examples of exhaust templates we use. |
|
 We prefer using Dykem Layout Fluid to allow scribing the port onto the rotor housing. The jars we sell (in the Tools Section) come with a brush in the cap. |
|
 By using a straight edge across the dowels, you make a mark on the rotor housing to line up the bottom of the exhaust template. |
|
 The port is scribed onto the rotor housing. Note that the template is aligned on the small mark made on the side from the step above. |
|
 This is about halfway through the porting process |

 This is a shot of a finished 12A exhaust port, from the manifold side. |
|
 Here is the same 12A “street port” from the rotor side. |
|
 This is a comparison of the finished port on the left, with an unmodified one on the right. |
