Would it just be smarter to replace the headers and the rest of the exhaust?

If i did mess with a Cat, i'd probably go with a dealer approved high-flow cat.

Here's another noob question for you... what if you added portholes or fender vents? would that decrease the motor heat by blocking the grill?

Again the goal of the grill block is to REDUCE airflow into the engine bay. Adding vents sets you right back to square one if not worse. Unless you have active grill shutter you'd only want to block some of the grill not all of it. Maybe play around with corrugated black plastic. Start with 25% of the grill blocked and see how cooling is then add or subtract since corrugated plastic is cheap.

Also the blocking can be inside the grill between the grill and radiators. The new vehicles with grill blocking tech all have them hidden behind the grill and radiators.

Oh no i understand what you were saying about reducing airflow and canceling out what i'm trying to do... i just didn't think fender vents would do that since they are facing the direction the air is already pushing and it would be a place for the air to escape. just my thoughts.

I like your idea of blocking the grill a little bit at a time.

I wonder if the 2013 active grill shutters would retrofit on our Rams. This would eliminate any heat concerns.

there has to be some direct airflow thru the radiator (most of the time). One thing I thought of trying if i were to close the grill (track mod), is to run ducting from my foglight holes to the front of the radiator. then you don't have the parachute effect like when the grill is open...

That is genius!! What I'd like to see if there is a way to simulate that in a wind simulator program to see if it would work.... Or... Make my own wind simulator with colored water and take a model dodge ram... Tweet it and see if it works.
