1.Same suspension as the f350.
3. Common problems. Dpf (diesel particulate filter) clogs and stays in cleaning mode. Cleaning mode (aka regeneration, or regen) uses diesel fuel dumped into two cylinders on the exhaust stroke so that it pushes it into the exhaust then burns it to convert soot into a fine ash and blows it out the exhaust. This process produce very high temps which long term causes other problems.
Other problem are leaking radiators, leaking egr coolers(not as common as some people let on) high pressure fuel pumps are known to go if the fuel system isn't religiously maintained(changing filters every 10000 miles or sooner and draining water/ fuel seperator monthly).
4.biggest reason for egr and dpf delete is reliability. Egr(exhaust gas recirculation) dumps exhaust gas back into the intake in an attempt to lower emissions output. Bit good for the engine. Coats the intake manifold and sensors with an oily black mess. I recommend deleting. Off-road tuners also shut the egr off so it's not operating but still in place.
The dpf which I tried to explain is the biggest problem with these trucks and most people will agree that it's best it delete if possible. Some places make it hard to do because it's required by the EPA and the truck won't pass emissions inspections without it. Also you need an off-road tuner for the truck to run without the the dpf and egr. Best tuners for egr and dpf delete is the H&S, Spartan and sct with custom tunes. These run anywhere from $1200 to $1800. For the off road versions. They getting hard to find and the prices are going up.
5. In my area I would expect to pay from 30,000 to $35,000.
6.best programmer ^^. All of them offer tunes from 50hp to 300hp.
7. Good exhaust brands. Mbrp, diamond eye, flo pro, and more. All about the same. They offer stainless and aluminized steel. Up north go with stainless and if you live south aluminized is fine.
Assuming you are deleting dpf. Want quiet? Leave muffler and get a dpf delete pipe(and tuner of course), Or a 4" system. Louder? Straight pipe with 5" system. Most people will also recommend a down pipe also to increase flow and reduce egts. It's almost useless to put any type if exhaust system in if you are not deleting the dpf, unless you are going for looks. The sound won't even change much the dpf in place.
This is the best I can do in an attempt it explain on one shot. There is also a sticky thread at the top of the page by country aggie that explains this quite well.
