The entire team at Bulletproof strongly believe that resetting the ECU and then dynoing it immediately after could be the cause of the low numbers.
From my 9 years of personal experience with Hondas, and from what I have learned, the ECU needs time to relearn its settings after a reset. I have heard that it takes even up to 30 minutes to learn new trim settings.

An aftermarket Ferrari exhaust without catalytic converters or headers runs $4-7k and typically adds zero horsepower. A full set-up with cats/headers/exhaust will run $9-15k and adds at best 15-16rwhp.
Granted your car is not a Ferrari, but people do spend that money on a regular basis for exhaust systems and could not be happier with them regardless of power gained.
You lost 51lbs, you have an exhaust that sounds AMAZING, and you own something rare.
To throw it into perspective, manipulating a dyno graph takes about 10 minutes of swapping out a sensor. If you honestly think some of these guys have gained 10-15whp with ANY exhaust for their S2000 they are merely a victim of a shop or manufacturer that is lying to them or a broken ass dyno.
I lost way more than $6,900 in the stock market last year, so hey at least you have something to show for it

If I had it to do all over again, I wouldn't change a thing! Thanks!

Yeah, hundreds of people from across the world are victims of broken dynos and shops swtiching sensors to lie to them.

I forgot to include inconsistent dyno'ing.
So many people dyno back and forth on different dynos (even if the same brand), different temperatures, different days, etc.
I can take my car to dynojet Y and get a 200whp run and then go to dynojet X and get 210whp and convince myself that it was an exhaust, when in reality it's nothing more than dyno discrepancy.
The below is one of the best selling aftermarket products in the world and there are hundreds of dyno sheets to "prove" that it increases your horsepower by 10-15%, I guess that means it's legitimate.

Now, I know nobody out there want's to believe it but
I must report the truth.
I lost 50 rwhp.
Just think how much would I have lost if it had been a Mustang dyno? Maybe 30 rwhp?

Yeah, you're completely right and everyone else on this forum is wrong. You've figured it out, congratulations. Because I'm pretty sure anyone who has had any real world proper consistent dyno testing knows that an exhaust on an S2000 doesn't increase horsepower by more than 1-2.
If I'm wrong, I'll admit it but instead of posting any factual data you're just rolling your eyes and playing the sarcastic card.

^ well lol, you are very wrong. single 70mm with no cat = actual whp gains of 10-15+ whp.
Go take a trip over to the naturally aspirated forum and post in the official exhaust thread.
