Being a turbo diesel you should be fine... Believe it is written in the fine print somewhere that a turbine device is a muffling device...
Of course it is still against federal regs to modify exhaust system period so...

I was told that a couple years ago. Been inspected twice with no problem. Print out this for your mechanic:

Muffler defined: Muffler is a device consisting of a series of chambers or baffle plates or other mechanical design for the purpose of receiving exhaust gas from an internal combustion engine and/or turbine wheels for the purpose of receiving exhaust gas from a diesel engine, both of which are effective in reducing noise.

If your truck came from the factory with a cat on it, it then must have a cat. There is no restrictions on mufflers thus far in Texas unless 07-08. We do state inspections and so far thats the law from my classes. The turbo is classified as a exhaust restriction so... But the federal deal also applies, as stated above.

Been through this more then once with a judge. Some say it's a noise thing others try to say it is a muffler thing. Registered commercial or not you must have a muffler. One trick to it though, if your pipes go upward its legal. So stacks is the solution.

According to federal regulations its also illegal to modify fuel systems, intake systems, and so on. But I don't see any G-men handing out tickets yet.
