Default Results of installing TSP 1-3/4" SS headers on 2500 4x4

Here is a writeup of my recent experience with TSP 1-3/4" SS headers on an '01 2500 4x4.

Texas Speed & Performance 1-3/4" Stainless Steel 1999-2007 Truck Headers

Before I ordered, I asked TSP if they will work for the 2500 and they said yes. $360 delivered to my front door with new gaskets.

Basically, yes they do fit, but there are a few small issues:

1. On the passenger side of the 4l80e tranny belhousing there is a small "ear" that needs to be cut off. This "ear" does not have purpose that I could tell (no bolts or seals) so off it came.

^the yellow particles are paint chips from my reciprocating saw blade. It doesn't show in this angle, however there is about .25" of clearance there.

2. The exhaust hanger/tranny heat shield assembly needs to be completely removed. The passenger side LT collector dumps straight into where this thing is located. You will have to fab a new hanger, or run without one. I am currently running it without one.

3. On the drivers side, one of the primaries has an extremely minor clash with the U-joint bolts on the front diff input shaft. They didn't even touch until I hit a bump during a hard corner. The clash resulted in no visible damage to the header primary, and a very slight corner-rounding of the bolts on the U-joint. It made a brief noise, then it was over and has not come back in a few days of driving.

I hope this helps someone searching for this issue in the future.

Good info, very thorough as always

I believe most every body with a 4L80E ends up cutting that ear off, I did.

I dont think the heat shield problem would be a problem with the 2500HD trucks with the factory 1.5 body lift

The heat shield is mounted to the transmission, and its a major clash with the header 3" collector (for these specific TSP headers). I don't think a body lift would make a difference here, but I could be wrong.
