ok well i just put on a new cat and its lready rattlin inside!!

i think im going to take it back and have them just drop it out or replace it for free, or replace it with a striaght pipe!!

what do you guys think?

 

I think your rattlin is a heat shield.

 

regarldess whether its the heat sheild or cat i would take it back and make them fix it.

 

its the honeycomb stuff insie of it thats rattling!, but why already?

 

ive seen muffler shops accedently drop em durring installation and just pick em up and work on em again. could have been handled improprly during shipping. doupt it has anything to do with your car

 

well i may just try to have him just cut it off and put in a striaght pipe and run no cats!!
