Yes you can .....best to have a turbo to cut the noise though. In Canada any vehicle above 1995 OEM equiped with a Cat MUST retain it on new exhaust installs......

I'd be surprised if yours even had a cat, mine doesn't.

I'm not sure about the cats, but it might depend on where it's registered. In the Milwaukee county area they have emissions testing, but diesels are exempt.
