So I guess getting Cali CARB didnt happen? CARB is very unreasonable with their certification prices and requirements.
Understandable, Im so tempted to do this but kinda scared to cut my CT exhaust.

I hope you are open to producing more if the demand is there. Im really interested in getting one of these but its not really possible at the moment. The sound clips sound amazing. Keep up the good work.

Just took a quick read through this, and your mid-pipe looks good!
Have you gotten the chance to test it on a car with the iVTEC conversion? I would think you could get the valve overlap you need to achieve the scavenging effect of the expansion chamber without the higher valve lift till later in the RPM range.
How much have you played with the location and angle of your divergent duct / expansion chamber volume to pinpoint and broaden the power "bump"?
Great work!

I have not tested my design concept on any iVTEC motors, but hope to sometime soon.
I tested many different variations of the expansion chamber to optimize torque and sound. In the end, we were lucky that the S2000 chassis allows such an optimal configuration.

I just don't have the time or energy it would take to do ongoing manufacturing and distribution when I already have a full-time job and a young family.
Id be extremely interested too in a few months time.

have you tried your pipe on the common Greddy SE duals?
that bastard drones a fair bit. if you can eliminate the drone from that, as well as get some performance gains, il definitely be keen to snap up one of your production models ..

I currently have a Greddy dual in my garage that I'm about to have flanged for a local S2000 CR owner (Driv300mph). I hope to do a "Drone-O-Meter" test on it before and after. I have no doubt that drone and performance will show the same improvements I've seen for every other exhaust.

^^^ And you can bet I'm looking forward to it! Both the Q300 and the Dingle have had absolutely no drone. Q300 is actually pretty dang loud... louder than my Greddy SE Duals. However, the cabin is nearly resonance-free while at the same time BLASTING sound out the back. I'll try to take another clip to see if I can capture the exterior volume.
If you hate drone, you'll love the Gern-Pipe. Not to mention the huge bump in torque through the midrange
