Cat Converter
 

is it ok to just have a gutted cat or should u straight it

just straight it unless you need it for inspection then gut it. If you have a MBRP exhaust you could get the cat delete pipe and just install the cat back in when inspection comes up. Hope this helps! :c:

Depends if you need to keep the cat or not.

no cat needed just askin if it makes a difference

if not needed just stick a pipe on it, they kinda sound funny when they're gutted in my opinion
