Think my cat on my TJ might be startin to plug up. So decided to go ahead and do my exhaust. My question about the cat is does anybody know the difference from metallic and ceramic. I'm wantin to say that the metallic means that it might be less likely to break down when offroading. Just trying to get someone elses opinion. Thanks for any info.
