I have been considering two modifications to my 2003 Dodge R3500 Diesel. It is a 5-speed. I already have an Edge EZ power chip in the truck. What I am considering is installing one of those cold air intake systems. I think it costs around $300 for the system.
The second thing I am considering is changing out the muffler to a full flow-through (no baffles). The muffler costs around $80.
Does anyone have any experience with either the cold air intake or the full flow muffler? Any positives? Any negatives.
Thanks Bob
