Based on all of you guys' input, I decided to give the Ultra Copper gasket sealant, Nord-Lock washers, red silicone on the threads and aluminum sheet gasket stock a try on the exhaust. Todd torques the bolts to 100 inch-pounds so throw that variable in the mix too.

We'll see how well that holds up. I (and every one here) need a leak free exhaust system that will stay on for 200 flighst not just 2.
