So just for a hypothetical discussion, if someone were to run this header on a mostly stock engine, what would be the result of running it without the cat OR sensor?

You didn't get the email full of information and fancy dyno scribbles? It's good stuff for your situation.

The wait is finally over and they're out! Good luck to anyone getting them, hopefully they're as good as anticipated! I've put some aside waiting for them, but $1625 is out of budget since I'm a student. Guess I'll just read about em and dream..

I am pleasantly surprised at the price.
It's not as expensive as I thought it would be.
I'm also happy the gains mentioned are with the stock exhaust.
My main concern now is the sound, both tone and volume.
Is anyone planning on getting one right away?

Sounds good man, if it would fit with my turbo id consider it. Fingers crossed ill pickup a used one for a good price and put a 3" flange for my turbo down pipe.

Congrats to BHR! I must ask, are there any issues with heat? I would imagine that puts out more heat than the poopy stock manifold. Also (maybe I missed it) but what is the weight comparison to the stock manifold/cat assembly?

Great job Charles! I do have one question thou. I read the product description and i couldn't find a definite answer to if this will bolt onto an existing midpipe? Such as racing beat, turbo xs, BHR or the OEM? Maybe its just not in perspective but the midpipe offered with the header looks smaller than a regular midpipe. Thanks. i apologize for my ignorance haha.

There is an option to buy it without the short midpipe for $100 less, but it would have to be a modified midpipe to fit.

No need to be a smart ***... Can no one have questions? Just because some people arent as knowledgeable as you, doesnt mean you need to sling around your little attitude.

I have read through almost this entire thread. I am impressed with the dyno numbers posted for the long tube header compared to stock. I am just curious if someone can explain the science behind why the longer tubes produce greater hp verses short tubes. Or is there something more than just longer tubes?

Charles has indicated that there have been many iterations, and that each change he made to it produced a change in the output, including a few times he has noted that "one change made produced as much more gain as other popular headers have in total." Presumably this one change is not the length of the header, though it may be.
I doubt that Charles will publish the exact R+D he spent his time and money on, so you may never get a straight answer as it is unlikely that anyone else will take the time, trouble, and cost to figure it out and then publish free of charge.

I don't expect to learn trade secrets about this particular header design. I am more curious as to how Exhaust scavenging is different between different lengths of headers. I do notice that the collector is longer than most with a nice taper, which almost always moves more exhaust. I wonder how the absence of the air pump feed rail effects flow. I suspect exhaust turbulence happens on aftermarket headers as some gases travel from port to port.

not trying to be a Smart *** like 9K (*cough*lol*cough*) , but seriously, u can find answer(S) by a simple google search, u are not gonna get 100% what you need to know, but it will give u a general idea why is this happening.

Note that I'm not saying that scavenging exists, merely that I am open to conventional wisdom being wrong
