I don't really grasp to concept of closing perfectly good threads.

A post from Lost - If you got rid of the 2 1/8" choke point in the
cat flange, you did a good thing.
I ran and posted tests on back pressure by putting a boost gauge between the turbo and
cat. When I got rid of the 2 1/8" choke point and 2 1/2" all the way back, the back pressure went to 0.0 PSI and stayed there. With your 3" as long as you got rid of the 2 1/8" choke flange should also have 0.0 PSI back pressure.
My stock turbo spools up much faster too.
This is along the lines of where I want to go with the exhaust. Now we have an 8 year old exhaust with 140,000 miles on the
cat. I still think this is a necessary upgrade at this mileage. A plugging
cat will kill an engine as fast as anything
Does anybody make a 2 1/2" stainless high flow exhaust for these vehicles that installs as effortlessly as the 4" exhaust kits install in the 6.5 diesels?
Does anybody know of a good exhaUST SHOP IN Illinois or Indiana that does mandrel bending?
