Performance Mods and repairs
If I can get my current problem squared away with my 05 6.0, and after the warranty expires, I'm thinking of doing some minor mods.
I've read on here about cat delete exhuast and doing away with the EGR.
I'm considering a five inch exhuast system, done as described above, getting rid of the EGR and maybe that Banks econo tune.
What have been peoples experiences with dealerships when trucks with these types of mods need work? I'd let the service writer know up front all thats been done. My fear is, they'll refuse the work, or just blame all the problems on the mods and not be able to get the truck fixed.
Opinions please.

They are not big fans of the cat missing. Make sure whatever route you take with the exhaust, you can be able to put it back on when it heads to the dealer. Some delaers are ok with chips, tuners, etc. Some arent. Just have to ask. The dealer in my town sells tuners out of the dealership.

If your waiting til your warranty expires then it really doesn't matter all that much if you do the mods or not, they are still going to charge you full rate stock or modded. As to the exhaust, unless you plan on running major power(which would take more then just the usual tuner, and exhaust) a 5 inch is overkill, do you plan on upgrading the turbo or injectors etc...? I would also go with customing tuning that way if you do decide to go to more major mods, you have a platform that is adjustible for that as well. I would also add gauges, even though you mentioned only running an econo tuen and you could argue that you could get by without gauges with a minor increase in power such as a generic econo tune does, but it is better safe then sorry in my book. My dealership knows I run a straightpipe exhaust and they still work on the truck, like I said since your waiting til after warranty expires they shouldn't refuse work, just don't ask them to install the cat delete system because they could get into big trouble with gov't for doing that if they are caught messing with the cat. I believe with regard to the egr, you can electronically shut it off with custom tunes as well, others might be able to chime in on that.

Actually a lot of places won't even work on a vehicle without a cat, because it is very hard for them to prove that they were not the ones to remove it. That's why I think a bolt on cat delete pipe is the best idea.

That is very interesting, I have yet to hear of any place here that has refused work on that(not that there aren't ones out there). The only time that I have noticed them just not wanting to do the work is the actual removal of the cat, not complaining about working on it after the cat has been taken out, because the law doesn't stipulate that, the law makes it a federal offense to mess with it unless you were exchanging a bad one for a new one. So, I do have a problem with their reasoning, to me it doesn't logically follow, it makes me suspicious that it is a run around. However, a direct bolt on would help, just swap it out between visits or get a high flow performance cat.

If the cat is that big of a dea, I'll just leave. I don't think the power increase would be all the much anyways. I just don't want to find myself in a situation where every problem is because of the mods, just because they either don't want to deal with it, or can't get it figured out.

Dealerships not wanting to work on a vehicle with mods isn't so much a legal question, as it is a technical question. If a vehicle has a system in it that is diagnosed with comparing known values to values that the vehicle is displaying, you have a hopeless situation if it has something there that alters commands, and you dont have a baseline to go by.
