Cutting the cat
Ok so I got my 01 Ram with the 5.2. Putting a new glass pack on it but I want to cut the cat for better flow and better sound. Other then having a cel and it smelling weird, are there any reasons why I shouldn't do it?
And I live in Oklahoma where there are NO restrictions or vehicle inspections.

I have a gutyed cat. Theres deffinately a power loss. Also ever since I have been having idle stalling issues. Im not sayinng its from the cat my problems arent as bad since ive changed my iac and tps however from time to time it still does funny things, however I dpnt have tje defouler trick in fact I dont have a O2 sensor in,the front (will by,end of month) with that said if you are still going to gut the cat do as HeyYou said and do the defouler trick

I gained power and also burn less gas since replacing my gutted cat with a high flow magnaflow setup... (until yet again something else failed) I read many times and recently saw a video where they explained the truck will run rich with a gutted cat...my long term fuel trim averages are lower now and even though I was getting no codes from gutted cat my post cat 02 sensor readings (I did not replace this 02 sensor) are smoother now and do not jump all around causing the af mixture to be constantly adjusted...

"cuz it was clogged." are the key words here... bottom line the rest of the truck is designed to work with it ..removing it can have negative effects without any real benefits since High flow setups are cheap and work well...

Mine was gutted by the PO... I had more low end power for a whooping couple days till the engine started this mis crap... the 180 bucks I spent for the stainless pipes and cat were well worth it IMHO....
