Acura RSX Exhaust

I Recently Installed A After-market Cat-back Exhaust System For My Car. My Problem Is The The Back Pipe Piece That Bends Over The Axle Bangs...

I Just Installed A New Catback,down Pipe And B Pipe Exhaust System. However, I Seem To Hear The Exhaust Rattling And Shaking, What Can I Do...

I Have A 2002 Acura Rsx And A Couple Weeks Ago I Scraped The Bottom Of The Car On A Dip And It Broke The Exhaust All The Way Off... Right...
