05 Mustang FRPP Exhaust Kit Rattling Problem

[Judd22]

Just had the FRPP Exhaust kit installed last friday. It started rattling. When i acclerate it happens. When im stopped at a stop sign or stop light it does it. Took it back to the place that installed it today. Got it back and they said they tightend the bolts. Still does it. I know theres a thread for this. I dont feel like reading it all. If someone knows the solution let me know. Another question. I know its a V6. Its not gonna sound incredibly loud. Isnt it supposed to be a little louder or maybe sumthings wrong? sumtimes its louder than other times. Let me know what you think.

I have ran several after market kits that rattle when you accelerating. Magnapacks, my corsas, bassanis, it depends alot on the install. You can take away the vibration by tightening the clamp as tight as possible and if that doesnt work check the driver side rear hanger mount hitting the actual muffler casing itself.

Flowmaster, Pypes, Borla, and the SLPs were the only ones I didnt have issues with.
