weird noise from cat back

[pbizzlegsr]

the so called metal plate/metal guard..the things thats on top of the s pipe is what the pipes touching to make the sound..it seems to be bolted on..would it be safe and okay if i completely removed it..? that metal piece that is.

i removed only the last plate since that was the problem and didn't want to removed the whole thing since the guard was made for a reason. have u checked your cat shield? that could also be the problem.
