Removing the cat is not worth enough gain to warrant the hassle,even if you want to go to 5" you can still make it work.

It will only void your exhaust warranty. It will also lower your EGT. That is what I was told from a tech at Dodge.

The below info is from Dodge:

This info went out to all dealers. It applies to 5.9's and 6.7's. 5.9's don't have to worry about the DPF part of this, but the rest is the same for the 5.9L. Dealers are supposed to be on the lookout for these issues. This post is to help keep you informed...

PURPOSE:
• To advise of the inclusion of Exhaust After treatment components in order to be compliant
with EPA 2010 Diesel Emission requirements.
• To highlight the new vehicle limited Warranty Coverage associated with the installation of
aftermarket add-on components to a 6.7L Diesel.
• To provide cause and effect information for aftermarket add-on components to a 6.7L Diesel
engine.
TIMING:
Effective immediately.
ACTION:
The increased interest in aftermarket components and performance equipment, and its subsequent
installation by vehicle owners, has resulted in repair situations that may jeopardize the warranty
coverage of the vehicle. A reference sheet, included with this bulletin, has been developed to help
identify common 6.7L Diesel add-on components and modifications and their potential effect on
factory component failures. Please ensure that all service and parts personnel have reviewed this
document and attached reference sheet and refer to it if they suspect a factory component failure may
have resulted from a Diesel aftermarket add-on component or modification.
ADDITIONAL INFORMATION:
The 2007 6.7L Cummins Diesel engine package includes a number of exhaust after treatment
components which are required to meet the stringent 2010 EPA NoX and Particulate matter
emissions. The system includes a Cooled EGR system, a sulfur oxide catalyst, nitrogen oxide
catalyst, and a Diesel Particulate Filter. Installing any aftermarket add-on components to the engine
system could render these systems inoperable, or cause severe damage to the components.
Refer to Section 3, What’s Not Covered, in the Vehicle Warranty Information Booklet for complete
details regarding the installation and use of aftermarket components, highlights of which are listed
below:
TO: Dealer Principal, Service Mgr., Parts Mgr., and
Warranty Claims Administrator
SUBJECT: Warranty Coverage Guidelines Associated
With Aftermarket Add-on Components to the 6.7L
Cummins Diesel Engine Ram Truck

Warranty
Bulletin
Certain changes that you make to a vehicle do not, by themselves, void the warranties described in
this booklet. Examples of some of these changes are:
• Installing non-Chrysler LLC (“Chrysler”) parts, components, or equipment (…Chrysler
radio or speed control)
But your warranties do not cover any part that Chrysler did not supply or is not certified for use on
your vehicle. Nor do they cover the costs of any repairs or adjustments that might be caused or
needed because of the installation or use of such parts, components, equipment, materials, or
additives.
Performance or racing parts are considered to be non-Chrysler parts. Repairs or adjustments
caused by their use are not covered under your warranties.
Racing Not Covered
Your warranties do not cover the costs of repairing damage or conditions caused by racing, nor do
they cover the repair of any effects that are found as the result of participating in a racing event.
Note: This would also include the sport of Truck Pulling.
If the vehicle is believed to be abused due to the installation of add-on component parts or racing
activity, all information should be documented and presented to your District Manager for review
and possible vehicle component restriction.
If you sell and /or install Mopar Performance parts, refer to the Mopar Performance Catalog for
specific warranty coverage regarding Mopar performance parts, some excerpts of which are listed
below:
No Parts Warranty
As referenced in all Mopar Performance Catalogs, Mopar Performance parts are sold “as is”
unless otherwise noted. This means that the parts sold by Mopar Performance carry no warranty
whatsoever...The addition of performance parts does not by itself void a vehicle’s warranty.
However, added performance parts (parts not originally supplied on the vehicle from the factory)
are not covered by the vehicle’s warranty and any failure that they may cause is also not covered by
the vehicle’s warranty.
Note: For information related to the 5.9L Diesel, refer to Warranty Bulletin D-05-28.
Please ensure that all affected personnel are aware of this bulletin.
WARRANTY OPERATIONS
Typical MODIFICATIONS Found On Chrysler 6.7L Diesel
Vehicles
Turbo Boost Controllers
Manual or Electronic which increase the amount of turbo boost allowed by the ECM.
Turbo Intercooler Sprayer
Manual or Electronic which provide a cooling mist of water spray on to the intercooler. This
increases the cooling capability for compressed air, increases air density and produces
more power.
High flow custom air intake systems
Custom air intake systems allow for maximum air flow which increases power but may
reduce the filtering capabilities allowing more dirt to pass through.
High flow custom exhaust systems
Custom exhaust systems allow for maximum exhaust flow reducing backpressure and
increasing power.
Over sized intercoolers
Higher cooling capability for compressed air increases air density and produces more
power.
Oversized (higher boost) Turbo larger turbine
Provides more air and high pressure into the combustion chamber.
High performance Powertrain Control Module (PCM) or Engine Control
Module (ECM)
Greatly change engine calibration and performance.
Propane Kits
Liquid Propane Gas (LPG) systems add additional fuel to the combustion chamber which
increases power.
Nitrous Oxide Kits
Nitrous Oxide (NO) systems add additional oxygen to the combustion chamber which
increases power.
Oversized fuel injectors/fuel rails and regulators
Allowing for more fuel to be delivered into the combustion chambers increases power.
Diesel performance enhancing equipment.
This equipment causes the engine to make more power by increasing the amount of fuel
and air available to the engine.
Typical FAILURES Caused By Aftermarket Modifications:
Burnt pistons
Pistons, rings, and lands showing signs of overheating and burning. In many cases the
pistons may be burnt down the side of the piston skirt. In Diesel engines this can be caused
by performance enhancing devices adding more fuel to the engine resulting in much hotter
combustion temperatures.
Burnt valves.
See Burnt Pistons
Exhaust/Catalytic Converter Melt downs (melted catalyst bricks)/
Cracked manifolds
See Burnt Pistons. Very high exhaust temperatures due to very rich fuel mix levels and
unburned fuel entering the exhaust system.
Exhaust/Diesel Particulate Filter (DPF) cracked
See Oversized fuel injectors/fuel rails and regulators. Very high soot generation due to very
rich fuel mix levels and excessive unburned fuel entering the exhaust system.
Catalyst/Diesel Particulate Filter (DPF) straight pipes
An exhaust pipe installed in place of the catalytic converters and the DPF. This causes the
ECU to set codes and causes the system to be out of compliance for emissions.
Burnt or Blown fuel injectors
See Burnt Pistons. Fuel injector body cracks can result in raw fuel leaking into the
crankcase diluting the oil.
Spun Rod, Main Bearings and Blown Head Gaskets
See Burnt Pistons. Also, caused by higher than acceptable turbo boost pressures; rods,
mains and head gaskets can not handle the extreme pressure put on them by the
increased power.
Diesel fuel injection pump.
Look for seizure or cracks in the pump.
Repeated overheating
All of the above.
Transmission, Clutch, Driveshaft or Axle Damage
Diesel power enhancing devices can put excessive stress on transmission, clutch,
driveshaft and/or axle components resulting in premature failure re

Its a no brainer... take the cat off.. take a pipe.. Stick it down into the end of the cat.. Now take a sledge hammer to it until the guts of the cat fall out the other side... Put it back on the truck..

Now get a catback system of your choice and presto.. Everyone is happy

it also depends on what dealership you take your truck to.........the closest dealer to me is the Glendale , CA dodge dealer(which by the way are really good, but...), which they dont like the after market parts on the truck and will most likely not want to honor you warranty........but the dodge dealer in cerritos califoria doesn't care what i have. they even sell trucks that are heavily modified..............

Cerritos Dodge is a joke.They are so out of control they have a special Dm watching over them.
Way too many techs that don't know squat so they throw parts till it works :hehe::hehe:

Just wait until your warranty expires. You only have about another year left. The gain isn't worth it. Just think about if your injectors go out or something then they will try to blame it on your freaking exhaust system. Chrysler is desperate to get out of warranty claims right now since their forking out mega bucks for 6.7 turbos and DPFs. I bet these car makers would be in a lot better shape if they didn't have to deal with this emissions BS on the diesels.
