Changing Exhaust and Cold Air intake system ?

[w6pea]

Has anyone added an after market Cold Air Intake System to their 4 Gen. Ram and or added a larger exhaust from the turbo back?
Also does any one know if it will effect the warranty on our Ram Trucks?

I have read so many articles about how the Air Intake and Exhaust Systems are so restricted that the Cummins Diesel are de-tunned to meet CARB and EPA Laws. Any and all thoughts will be apprecaited.
Thank You.

Actually Ram has a higher rating than Cummins does. The highest rating for a 6.7 in the medium duty truck line is 325/750 @2600 rpm. Ram is 385/900 @3k+. I think the new trucks have a factory cold air intake.

Were those articles you read really selling after market products? With a replacement exhaust system, how are you going to maintain the emission system? Yes, altering the intake and exhaust could not only affect the factory warranty, it could also affect mandatory emissions tests. There are federal and state laws including stiff fines relating to altering a vehicle's emission system.

I understand that about effecting emission laws and warranty, I just wondering what can be done legally to give the engine better air flow, intake and exhaust. Or just leave well enough alone? I see people talking about Banks Systems etc. etc.to just name a few, but they all seem to be illegal in California. Or in any state that follows CARB regulations.

Close the hood and get behind the wheel. Only reason the open the hood is to check and change fluids and filters.

Have you actually purchased a truck yet. If so, why not list it in your signature?

OK found it! Nov 19th post by w6pea "I just ordered a new 2016 2500 Big Horn 4x4 CC/LB IL-6 6.7 L CTD."

If you got the 8.4AN and the 7"EVIC there is enough there to keep you busy the first couple years!!!!!!!!

Pat,
With the new trucks and with you living in California I would leave the truck alone.

First Calf. requires all aftermarket products that are fitted to the truck and could interfere with the emissions system to be CARB certified, most are not. Now the CAI ( air box) flows enough air to support the HP/TQ that the truck is making stock. Most CAI system say that you could see less than a 10% improvement when added. When I worked at Cat anything less than a 10% improvement in performance was ignored. This could be operator introduced and was very hard to measure and support in a second round of testing.

Now a Turbo Back exhaust system change would require removal of the DPF and any other emission rated components such as the DEF system. With this removal your truck would not pass the emission required testing and you could not license the truck in Calf. The newer design emission system with DEF has less issues then the earlier trucks built around 07.5 to 10 MY. If I was to purchase a new 15 or 16 truck the truck would remain stock.

Maybe I should just go back to bed......no better yet, drink some more coffee that is U. S.Navy CPO approved coffee! (coffee that will remove paint 2 fathoms below the water line) I think you guys are right. If Cummins wanted these features they would already come on the truck. Maybe don't even get into a Gear Vendor Overdrive set up. until we see what it will do. Thanks need more coffee, there's too much blood in my caffeine system.

"Maybe don't even get into a Gear Vendor Overdrive set up"

6th gear in both autos is 0.63!!!!!!

With 3.42 gears and the 33" tall tires at 80 MPH I was turning around 1750 RPM's, so put a shot of booze in the mug and sleep it off!!

Your new truck comes with a cold air intake........

Your new truck will not even have a "muffler" since the EPA stuff does a fine job of that already. My son added a 5" back pipe to his 15 3500 Limited and it gave it a really nice throaty sound but I really doubt it made a bit of difference in performance.

Really a nice ride at 103! 2011 RAM Dually with 3:42's.

 

[gsbrockman]

The intake (RAM Active Air) and fuel filtration are both reallllly hard to beat on a 2013 & up RAM CTD in my opinion. Really not much to improve on in those two aspects.....unless your billfold is too thick and you need to thin it out some.

Cold Air Intake systems. Better known as a CAI. If you review the stock intake air system, it's a CAI. It takes air from outside the engine compartment. Stock is from the wheel well, which is outside the engine compartment. So it is actually a CAI. Also, I have an after market CAI on my 5.9 only because I wanted it. The stock air filter system could handle up to 700 hp. Did I need a different one ? No. So if your looking to change your system, you'll be doing it because you wanted to. As for the after market companies saying up to 10% better mpg, well 0% is within that range so they are not lying.

I have a SS 5" exhaust on my old truck. My old 4" system would handle up to the same 700hp. My truck is mostly stock. I did it because I wanted to. Same choice is for you. Will you benefit from a bigger system ? Not really.

I call Cummins when I first bought this one and during the discussion I learned one thing. Dodge contracted Cummins for the engines. They had to meet the requirements from Dodge for anything away from the engine block and it's internals. So the air system and such is there because Dodge wanted or approved it to be there. The Cummins engine was made and assemble then shipped to Dodge for installation into the vehicle.

Being you live in Calif. consider this. I lived there for 40 years before moving here and have dealt with the famous Calif. DMV and their requirements. Save the headaches and stay stock. If you move to another state like I did and have no smog testing, (or the price you pay for the yearly tags) then have some fun.

Here is an upgrade you can do that will let you open the hood to do it. Only cost $13.95 plus shipping. I am thinking about a second one to go on a trailer hitch cap/insert.

I think I am just going to take the "wait and see approach" about any modifications to the new truck. "SWMbO" said that why spend almost $50K or more on a new truck and then put After Market Crap on it? If I want to modify something, take our truck that's over 20 years old, put a new paint job on it and take the gas engine out of it, and put a Cummins Engine or a Caterpillar Engine in it. Then leave it the driveway and let someone steal it, and then see how much our insurance pays off on it. My luck I would do all of the modifications and then it would get totaled.

So maybe on the new truck I will get it put a Camper Shell on it and then maybe some different Fog Lamps and some work lights and then a Warn Winch and be happy, oh and maybe Weather Tech Floor Mats. Oh forgot put an Amateur radio in the new truck.
The main reason we went with the Crew Cab is so we can have our luggage up in the cab instead of in the pick up bed when we travel.

I think maybe that would look great.

w6pea, over the years I had it pounded into my head, with diesels, first you open flow out, then open the air in ..... as much as you can. But I'm very well into my 6th decades of life and my teachings were *pre turbo days*. First thing I did was out of habit. Not so sure I'd do it again.

One thing I do still believe in, there is never enough filtration. Consider an oil by passes system with a 2 micron filter, (and oil lab tests) even a coolant by pass filter. Your truck is new and outside of your home usually the 2nd biggest debt a person has. It's worth the consideration of a few extra bucks. Now these are ideas to 'consider' for improving your truck. (And California DMV can't stop you.)

Then, 'when your really ready', have studied the improvements you want for your truck, there are one heck of a lot of aftermarket companies with all kinds of new and improved toys that will fit. Look at all the sponcers supporting this and ohter site. (And what the hell, Snoking's suggestion of the badge might be something to consider.)

Past the emissions equipment, the only restriction in the factory exhaust is the 1/4" thick ring in the middle of the resonator. If you remove that ring, the entire exhaust system is a smooth 4" dia.

 

[SnoKing]

Here is a small sample of what is happening. Our Son is a principal in a large exhaust wholesale company. In the last couple yeas they have completely dropped stocking any delete type pipe due to the crack down by the FEDs. My 2001.5 was modified with different turbo, exhaust, injectors and timing box. It however did not have a factory exhaust system that was part of a smog system and it was under 10K GVWR. I believe there is a federal law about modifying the exhaust of a vehicle over 10K. These new trucks have the power thing pretty well worked out and computer code that prevents them from hurting them self. Want to tow more get the lower gears! Cummins12V98's towing shows how capable these trucks are stock!

For me I am just going to drive and tow with it, and we are going to see more of the country with it! SNOKING

 

[kthaxton]

and then a Warn Winch and be happy, .

What kind of travelling do you do in a 2500 Diesel that requires a winch? In my old trail toy (86 Ramcharger) I did multiple trips to Moab doing reasonably hard trails and also have done many solo, multi-day backcountry trips that required us to live out of our truck for up to a week at a time. 200 miles off-road in some cases.....I have yet to need a winch, although I would have liked to have one.
