Florida Stang

Hello, I am new to the board. I just purchased my first 5.0 mustang(always had the old ones,69 and 71). It has a rattle under the car that I thought was the bracket loose at the end of the h pipe. The sound is coming from both the cat's like a clanging sound inside. Any ideas???? Is there something inside of those things that comes loose? Thanks for any help.

the cat could be bad

If it's an '86-'93, there was a heat shield that was put between the cat and floor board, that typically comes loose after time and rattles... Hope this helps...

cats are probably bad loose the cats and replace it with a offroad h pipe if your laws arent too harsh
