Looks like 5400 RPM is the cross roads of torque an HP mufflers or not. Very happy with outcome

Now......................anyone know how much torque an XR outdrive will handle?

Torque and horsepower always intersect at 5252rpm.....just so you know. Very nice #'s!!! Nice to see a build report back with dyno -sheets, doesn't happen that often, good for you man!
