Jamie, have never heard about copper being illegal for an exhaust. Why would that be?<br>The Jag I converted to dual exhaust used 2 inch BRASS tubing front to back. This was years ago and where I was at that time (Swaziland) legalities was unheard of.<br>BTW, the Jag was easy to convert to dual exhaust because it had OEM dual exhaust manifolds. <br>Is a brass exhaust also illegal in your neck of the wood?

Ya sorry I misread that yes brass and copper are illeagal here! How insane is that. Appearantly they produce noxious fumes when they get hot? I have no idea all I know is my uncle got booked huge by the DOT for having copper exhaust!.

Sounds a lot like bureaucratic nonsense to me. I can see it now.... driving down the 404 and harming the people in the cars behind you with all the noxious fumes POURING off a brass or copper exhaust. The quantity of noxious gasses coming off such an exhaust system must be unbelievable!!!!!!<br>Please don't pardon my sarcasm. Would love to meet the individual that dreamed this one up. Not to mention the idiotic politicions who actually allowed this law to pass.

I remember reading through the forums when I first joined, and the common consensus was that Diesels don't produce water as a byproduct of combustion like gas engines do,<br>therefore,<br>we don't really need the expensive stainless exhaust.<br><br>Aluminized should be just peachy for many years.<br><br>Unless this school of thought has changed in a year?<br><br><br>phox
