Honda CBR400RR-R NC29 ('95) - Engine Fault / Exhaust Noise (SOLVED)

What was the outcome? Exhaust gasket or badly fitted aftermarket system?

Cause was a loose flange plate in the collector (4 into 1). The design had the collector as the lowest point under the bike. Removed and tac welded the plate to cure the noise!
