I thought the same thing with my Bing’s Exhaust and it still broke.
It never pays to ‘save money’ by buying cheap crap.
In the end I replaced the Bing’s with an RSR GT-II, if I had taken the money I threw away buying a shitty knock-off exhaust from bing and added it to the money I had to spend on the RSR I could be rocking a sweet titanium exhaust right now with double plus baller points
