Great information. I have the same type of back fire that occurs when I come off of the throttle after hard acceleration. Always assumed this was due to a rich fuel mixture, but I do have some minor exhaust leakage where my side pipes slip over the headers (not a flanged connection), which may be where the detonation is occurring. Any suggestions for sealing this area (sealant, heat resistant tape)?
