Are you sure the stockers are UL? This being a V6...UL headers cause pulse crams that negatively affect performance. I would think Nissan put EL headers from the start, I was under that impression.

My old Eclipse GT with the RIPP long tubes with a tune netted me 38whp, so I dont see why these wouldnt make quite a bit of juice.

Stillen headers did not make 10-15hp. I'm not even looking for more than 5whp from the FI, I'm only looking for how much torque they will pickup...since thats apparently LTH's claim to fame.

i am impressed that you want to go the distance with this project to ensure the best possible gains across the board...

highly respectable and look forward to the results of the next phase

Highly respectable that he does research on a product he is developing? come on, he is doing what he is supposed to do.

I'm ~fairly~ certain. I seem to recall getting that from Josh, but it's been so long I can't say I'm 100% on this. So take it with a grain of salt, I guess. If the stockers are EL, then I'm not sure what the advantage of aftermarket headers would be, at least in terms of regular-length ones. I don't think they're wider diameter piping, are they?
