I was building some shorty headers for a turbo setup and came up with this to replace the plog,with this shorty and a 2 1/2" crossover and a ported rear with a 3" dp you should have a good setup,

Isn't it going to have to make a sharp 90* bend immediately after?

That would be a funky looking header. I don't think there is even room with the radiator fans.

That's beyond Plog that's a dang header!!!!!

Tuned length would be hard with the amount of room to work with.

Well to be honest the biggest downfall with current designs is the small crossover it should be at least 2 1/2" ,but looking at the plog not a bad design but lengthening the primaries to a bigger collector then using a bigger crossover should greatly increase flow ,this design is just a trial piece I may change it to incorperate the crossover and front as one piece and put a cutout for a turbo that can be capped or not ,just thinking out loud.Chico(pops)

Anyone have any test sheets or data sheets on the differences in primary lengths on the 3800?
The pros by having same length primaries.
