Cut a long story short I found a guy on another forum who works on 4x4s and paid him money. Not very much as it goes but he asked me to be hush about that bit.
It took time to work out the details but finally the truck has a massive pipe out the side and sounds like this:

I love the sound the turbo makes as it unloads. thats amplified with more load. It runs better and it feels more like a car now. Rather than a land slug

I went for a 3'' seperated wastegate downpipe from the turbo to a 2.75inch main pipe. A single 12'' long hotdog silencer in the middle and then a slash cut side exit.

Guy called stringer runs overfab in westbury. He has loads of fab experience and turns out good work.
