That is correct, the reasoning behind it is that under the right conditions exhaust fumes can severely limit your visibility if the exhaust exists before the windshield. The only exception to that are Class 8 straight trucks with tanker bodies on them, they often have the muffler right behind the front bumper with the exit on the passenger side, this is so if there were ever any sparks to come out of the exhaust they cannot ignite any vapors from any flammable liquids the truck may be carrying. A pickup truck does not haul flammable liquids, so you do not qualify for this exemption - your exhaust needs to exit behind the cab, whether you run a stack or a side exit or all the way out back.

While they are right, some states do not care enough to check things like this? WHat state are you in, does it require a yearly inspection and/or smog? If so you probably need to fix it, but states that do not I would not worry about it. I definetely would not do anything until someone made me.

I dont think the cops would give you any trouble, just take it nice and easy when they are around, lol i take it pretty easy around cops with my straight piped '94 and the cops never give me a second look.

That is a sweet truck. 2 tone color, trim package and everything. My dad had a 75 camper special that looked identical to yours in body and paint. 390 on LPG though.

Nothing wrong with banks, but fitting the turbo might be a challenge in that truck. I heard some guys had to hack the firewall to make it work.

REALLY interested in the intercooler you are doing in this. To my knowledge there are no intercooled turbo diesel IDI trucks from the 70s running around. I've seen turbodiesel repowers before, but never an intercooler (or allison for that matter!).
You are breaking new ground.

Over here the exhaust must exit 1 foot behind the last opening window. With my slide open rear window that means no cab mounted stacks at all. The reasoning is not so much vision but exhaust fumes entering the cab and suffocating the people inside. Carbon dioxide and cabonmonoxide have no smell and so can sneak up on you. Fact is though if your carefull probably would look pretty cool and most cops wont care or know any differently.

The fumes and behind any opening into the passenger compartment is the reason and rule here.

Unfortunately, the first rookie straight out of the acadamy that sees you will probably be pulling you over.

Those trucks with stacks out the hood are pulling trucks, not street legal.
And those guys are not in the truck long enough for the carbon monoxide to get to them.

Hey guys i have a problem with my truck now, its the fuel pump i think cuz my diesel runs out of fuel and shuts off, i have an electric fuel pump "Purolator Fuel Pump: Universal; Electronic; Solid State; POSI-FLO(R) Pump; 1.5-4 PSI; 25 GPH; 95 LPH" from kragen, i think i need more PSI right??? and i noticed when it shuts off i stand next to the fuel filter with the fuel pump on and notice that it makes a sound that the filter is filling up with diesel fuel, meaning the filter goes bone dry, and yes i do have diesel fuel in my tank Any ideas???
