On a side note if a bill passed today in Cali that all motorcycles 2000 yer and newer will have to start smog checks as of 2012, there trying to lump diesel trucks into it also, if they find any performance parts it wont pass the visual check so if your truck is not stock it wont pass. the cost to change mine back not worth it. guess time to buy a older than 2000 or brand new truck.
Just curious, what is your source on that. Not saying that I doubt you by any means. But I live out here in CA and my truck is right on the cusp and definitely not stock. I've heard about smogging diesels, but haven't heard of it being a retro-active deal.
On that note, a friend of mine, got a $2500 fine for modified emissions for an AFE intake on his 06. I have heard a lot of stories of 04.5 trucks getting busted for no cat or modified emissions, but they aren't writing up any of the older trucks.
Sorry to get off topic.
