Ordered a Northwest Offroad (NWOR) header

I was under the impression that this header was the best one for low end gains. In fairness, I do believe this header helps going up mountains, but nothing that impresses me considering the $600 I invested in it.

 

Doing a little research, I found http://www.autoanything.com/exhausts-mufflers/long-tube-vs-short-tube-headers
which states,

and that

Well, there is more about it here: https://www.physicsforums.com/threads/long-tube-headers-vs-short-tube-headers.208674/#post-3477081
in that

I touched on this subject a little in my own post, trying to reflect on the information and give myself some kind of understanding of what is best, which is in the Performance and Tuning category: https://www.tacomaworld.com/threads/conclusive-theory-on-design-dual-outlet-flange-dual-cat-c-a-r-b-california.529120/
though my thread kind of bounces around why short headers are better for 4 cylinders; my main gripe was why my stock exhaust features a Dual Outlet Flange.

Anyway, I've got errands to run!
See ya'll later!

 

@chris4x4 did some dyno testing and confirmed that the NWOR header was the best header for low end torque.

Your post has me thinking to staying with my LCE header instead of trying to get a NWOR header.

 

Yep, if you already have the LCE, I'd not worry about switching. Being that your SC'ed it may make more of a difference, but I doubt you'd be able to tell the difference. I did several timed 0-60 runs (before and after) using a stop watch and shifting gears at red line as consistently as I could and the numbers were nearly identical.
