My 1970 Slow Poke Nova Build

If you're going to put on an exhaust system, on my 1969 Camaro Z/28 I have a 2.5 inch flowmasters with electric cut outs. The car will run only .15 to .18 slower through the mufflers rather than open headers and they are pretty quiet. Just a recommendation from experience. What I do is run the car with open cutouts, qualify with that number, make a pass with mufflers and dial the car through the mufflers.
