Im getting a code on my 5.5 gen and was told it could be due to a clogged cat. i was looking to gut it this weekend.

if i gut it how will it sound??
Is it OK for me to do so??
would it be better to do a straight pipe??

What if any problems would i run into??

 

this is basic stuff, not advanced performance talk - has nothing to do with headers, internal engine modifications, advanced engine management, etc.
