Going Ahead with DPF.

Never heard of anyone getting their truck impounded. Have a friend who works for Blue Ribbon Dist. here in Phx, they have 19 trucks ranging from new to the oldest is a '97. They got fined once for $1K, that's the only first hand knowledge I have of anyone ever getting fined.
I think I might have seen CARB one time at the rest area on the Eastbound 10 in Calimesa, but I was in the hammer lane with my foot on the floor getting a run up the hill-so I didn't stop.

 

Well, if the fine is a thousand bucks, I personally would wait til I got the first one.

I was at a shop in California getting some front brakes put on. They had a county owned dump truck in the shop also. The shop had installed a dpf on that older truck. The problem : that dump truck wouldn't run.

Good luck. Maybe some people aren't having problems.

 

My install will be one year old in April. No issues at all mechanically except for the pyro running just a hair warmer due to some back pressure but I guess it's normal, I have been running 7" straights which had zero back pressure, now with the install, I have some and still running straights. I have modified file in the ECM, (1LW series 550 Brakesaver, with 58's injectors and better fls/fts numbers). In all, the pyro "post" won't go over 900. Still averaging 7.0 and sometimes low as 6.5 on the heavier haul loads. I had the R-50 install which covers for bigger horsepower, 600+ easily, but more expensive. Like they say, "Horsepower cost money". The R-40 will handle up to 475 HP, but my installer said he has had them install on stock 550's. I can only speak for Cat engines, but I have seen them alot on Detroit's, and the few I have spoke with, told me t no issues either. The key is keep your eyes on the gauges on a hard pull.

 

Very interested to follow your progress, particularly with the 12.7. I didn't want to be the guinea pig -- especially since I didn't qualify for a grant.

 

Like you said before @areelius, it's a numbers game, and I've always been pretty lucky. So I'm going to play the numbers game until I get caught, along with the thousands of other trucks I see rolling around LA on my weekly trip.
I think I would like to talk to an atty. to see if they can really impound the truck as hundreds of others are driving by that are non-compliant.

 

I couldn't find anything from them saying that they will impound a non-compliant vehicle.
