2Bros M5 Carbon Exhaust Installation Help

Hello Group,
Just Installed 2bros M5 Carbon low mount exhaust on my 95. Sweet low rumble not HD insane loud. I've noticed that the 2bros S-bend pipe that connects to the header collector has about a 1/4in play left/right. The clamp is as tight as it can go but the play is there. Any suggestions on how to secure the S-pipe more firmly? 2Bros directions stated to reuse the stock gasket and clamp, I didn't see any gasket when i removed the stock pipe. Is this gasket a normal part?

Thanks,
TWeber
