Hi Frank
Do I remember you posting before that you cut open the splitter box under the gearbox to see what was inside? If it was you, would it be possible to cut open the box with an angle grinder, , remove the innards, and weld it up again? Is it stainless?
I can't afford a new header but have the tORs so thought this might be a halfway house to remove some restrictions, and I'll spend my money on a dyno tune as I have Tune ecu already.
hope the Jars do what you want!
