Just tending to a few small things I can fit in between the house renovations.
I didn't like was the exhaust support rod only going halfway through the bush. Not sure if it is due to the different transmission and transfercase the 5.7 has compared to the 6.1 that the pipes were made for?
Support rod fitting much better now after cutting off the old one and moving it forward.
I got my replacement high flow 3" Kooks cats made by GESI. They are the same diameter as the little resonators the mid pipes had where the cats normally would go so made them an easy fit.
Welded in the first cat that is under the transmission pan. Was able to get it to sit a bit lower to get a bit more clearance above it.
Can also see how much smaller they are compared to the factory cat on the right.
With the extra clearance gained I had enough room to fit a heat shield above the cat to reduce the radiant heat effecting the transmission pan above it. So I decided to make it from the factory cat housing. Here is what it looks like after cutting it in half.
Ground the ends of the cat housing out until it sat low enough over the pipe while still leaving sufficient air gap to the cat underneath.
Can see the air gap left. I may use the other half of the housing to fit over the second cat as well to keep the floor cooler.
Can see the heat shield in place.
