So, my catalytic converter on my '97 2.5L is going bad. It's not throwing any codes (yet), but it has an incredibly annoying rattle at idle. Mechanic and I have narrowed it down to the cat. I have been researching and I cannot seem to find a very cost-effective solution to this problem in California. My logic is, if I'm going to have to have an exhaust shop cut out and re-weld in a new cat (I'm looking at this one: Magnaflow 418036), might as well replace the whole exhaust while I'm at it. It would be easier/cheaper to replace just the mid-pipe/cat combo (like this one: Header Pipe with Catalytic Converter) but, ExtremeTerrain responded that this is not CARB compliant.

Is the best option if I want to replace the whole system to get new mid pipe, new CARB Compliant CAT, and Baker CARB Compliant cat-back exhaust?
I understand this isn't going to do anything in terms of power gains, my gutless 2.5L doesn't need it. But if I have to take it to an exhaust shop anyway, might as well replace the whole system, right? If I have to spend $450 on just the cat, it's not that big of a step up to replace the whole thing. Talk me out of it. Lol!
 
I see no real not to. Just make sure you've done your research. I don't know how that's going to sound, but it may or may not sound louder than you want it to.

Thanks Chris! I’ve heard good things about the Banks exhaust sound. Not too aggressive (apparently). I think it would be silly to have a gnarly sounding exhaust on a jeep that can’t go faster than 70 mph 😂

I saw something many many years ago that I will never be able to un-see. It was an early 2000's mustang. It sounded weird, and looked weird. Upon getting closer at a red light I noticed it had a tin can muffler, and the biggest rear spoiler I had seen to that date. Basically some kid turning an 'American muscle car" into a rice rocket. I wish I could get that out of my head. And this was probably 15 years ago.....
