No emissions checks down here in FL, but I still have cats. They have minor effect on performance and it really makes a huge difference. I'm no tree hugger but I try to be responsible when it's easy and realistic. I have to admit I have gutted cats on past vehicles and am thinking about doing so on my current ram but am really trying not to lol. I think I just want to do SOMETHING.....can't sit still...

this is how for me... unless you cut it open you can't tell there is no catalyst in it

but, when I do go in for inspection, I do swap the lt's and gutted cats for shorty's an stock cats...I just tested and passed last month but since I'm not racing for awhile I'm going to have my tuner take a good look at the data logs and tweak the 'legal' setup... I could tell it doesn't perform as well as the lt's but it still feels peppy...
