I'm skeptical that the shape of the stock manifold and header will work well as the manifold and header of a tuned pipe.

But, I'm not a pipe expert, and results are results, if it works it works. It seems like it would be an awesome idea if it does work as the cost of just the chamber could be way less than a complete pipe with manifold and header.

I'm seeing many obvious advantages, but nobody doing this. Either there is a hole in the market that I'd love to see filled...or it's not being done because it doesn't actually work.

3 spray bars could be easily added, 1 at the bottom of elbow near bolt flange, 1 just below the rubber boot and 1 in the pipe right after the boot. Inject at the location that best fits your power needs and adjust flow with jets. Could add Ewic too :)

Wasn't there summer aftermarket company that made something like this because in the day? Like Coffman or Kerker or some such? I vaguely remember seeing a picture. Half pipe chamber type deal that fit on the stock header like this or you could replace the stock manifold and header with an aftermarket set that worked with the same chamber.
 
Not so much level of restriction as shape. A tuned pipe relies on a divergent cone to create a negative pressure wave, the placement and shape of that divergent cone is important for the timing of that wave to work correctly. There is nothing in that manifold and header combination that looks like a divergent cone to me until you get to the add on chamber and it seems unlikely that the timing will be correct by putting it there entirely based on where it fits working with the stock parts rather than putting it where it needs to be.

But, maybe it does work. Maybe the divergent cone in that chamber is not ideal but still effective enough to work decent. This is all pure speculation on my part. I'd love to see it work.

I agree, the stock manifold looks like a pretty poor design in comparison to other "tuned" exhaust systems. It's basically two runners just crashing into a 90 degree log, no thought seemed to be put into blending the transition of the runners into the chamber/headpipe. WIth that said, I think the chamber design is still a big improvement over the stock chamber so it likely would make more power. Not sure how they are handling the water inside the rubber elbow that cools the "headpipe".
 
If the protec or the other Aussie system really worked,wouldn’t you all think it would be all over the place like the Bpipe?
Just sayin!

If you had a forum of people all of sudden say it was the greatest thing since the bpipe it would.. Just like how a few years ago the 61x cylinder was the only thing to have and now everyone wants 64x cylinders. "BroScience" leads our market. =/
 
Yes but it didn’t happen even when protec offered theirs.a bit telling of the outcome IMO.
