The last steps for me where to cut the cooling inlet and exhaust. I used a dremel on the cowl. I put painters tape on the cowl and penciled in the shape I wanted then opened up using a dremel.

For the exhaust cutout I used the template supplied in the kit. I taped in place using painters tape and once I was happy with the location I used a sharp exacto knife #11 blade to rough cut it out. Then I used a dremel with a small sanding drum to finish while the template was still in place to prevent me from taking too much material.
