Well, we have a theory on the pinging sound... when I took it to a shop to get the pre-mufflers and cats taken off, they used 1 3/4" OD tubing... and we figure its just the resonating frequency of that tubing that is causing the pinging sound. But, you guys should get to have a vid clip HOPEFULLY tomorrow of just driving around, it sounds so insane at just cruising through city speeds, I mean, it sounds so close to the 4.6L out of the Mustangs its scary.
