I'm at the stage of securing an exhaust setup. How do you guys do it?

I'll have a sub-cowl under the belly of the plane (shape of a tear drop), which will streamline the main cowl air (coolant and oil outlets).

I'm thinking I exit the exhaust (2.5" pipe) inside the sub-cowl and have a 5" wrapped around it which ends out the sub-cowl for x length. This should help create a vacuum and pump out the main cowl air.

Before exiting the main exhaust pipe, should I have perforated holes or louvers in it?
