Exhaust Ports:

Detailed Description

CNC-laser cut stainless steel porting template for 12A/13B 1st. generation(SA/FB) cars, built from 1974-1985, this exhaust porting template kit includes one aperture template and one aligning jig. Unlike other templates, the holes are already cut for you. Just spray or brush Dychem or similar Layout Fluid on the porting surface, then scribe the port outline using the template onto the layout fluid stain.

Pick the exhaust aperture template from the drop down menu. Please be careful to choose a template for your engine, 12A vs. 13B. We generally recommend you use the matching template for the intake template you picked, i.e. use a medium exhaust template with the Medium Street Port Intake template.  More experienced engine builders might choose a template other than the recommend one. Using one step smaller will tend yield a broader powerband with less peak power, a step larger a narrower band with more peak power.

For Off-road use only.
