how does it sound in the cab, like how she barks but it seems like its loud in the cab... is it?

and also if you delete the catts and straight pipe it would it pass emissions in NY, bc i know a gass truck wont pass, but im still dont know much about diesel testing

You'll need to check local laws, BUT (in theory) if it came on the vehicle, it needs to stay on the vehicle, emissions wise.

No, it's not that bad. My truck has no cat, but it's got the stock muffler, and it sounds virutally the same. The muffler by far makes the most difference.

Just get a good muffler, or no muffler, and you'll be fine. If they do emissions testing you'll have to keep the cat, but I'm not sure if there's a restriction on mufflers...
