Is this horse power gain true
True Dual Stainless Steel Cat-Back™ System
Borla Performance Industries offers an incredible stainless steel exhaust system for the popular Nissan 350Z. Borla was among the first with a bona fide performance exhaust upgrade for the original Z cars. The new Borla Cat-Back™ System (PN 140045) is a true dual exhaust with the famous Borla XR-1® Race-Bred Mufflers. Independent dyno tests have shown incredible gains in the 20+ horsepower range. When complimented with the Borla custom fabricated stainless steel T-304 Headers (PN 17221), power numbers as high as 24-horsepower have been observed. Unlike other aftermarket exhaust that actually loose power in mid-range and low end, Borla gains through the entire RPM range. Serious performance enthusiasts understand that true power gains are not simply a big number at max RPM but rather strong torque gains over the full curve. The famous straight-through, patented designs allow Borla exhaust incredible flow increases. The Z car flow numbers improved 27% over stock! Flow makes power. Simple as that! The Borla true-dual Z-car lightweight T-304 stainless steel system actually weighs 12 pounds less than the factory single exhaust. Add to this package a great look with large 4” angle cut rolled edge polished tips and that famous Borla growl. Once again, the genuine Borla exhaust puts the Zoom in the Z car. Isn’t it time you stepped up to Borla?
Borla Performance Industries, the original pioneers of aerospace-grade T-304 stainless steel (superior to T-409 or aluminized steel) free flow exhaust utilizes its patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy – all with an easy bolt-on installation. All BORLA street products carry the famous BORLA written million-mile warranty.
tis is for the HR

Who did the tests?
When was it done?

I may be totally wrong here, but I'm beginning to suspect that, in order to measure these "gains," they simply (and ethically) dyno'd the car, installed the new exhaust, flash-tuned the ECU "to adapt to the new mod," and then re-dyno'd it.
A "tune" alone can easily add 10hp to the stock numbers if it was not a very well-tuned car to begin with, and I guess maybe the addition of true dual exhaust PLUS a re-tune might yield somewhere in the neighborhood of 20 hp. Maybe.
That would give them the paperwork to back up their claims in case they were ever challenged (say, in court for instance), therefore making them bold enough to put it in writing in their sales literature.
That's just a guess, but it is the only way I can fathom some of these wild claims from some manufacturers for an exhaust that retains the catalytic converters.

You do 3 pre-install runs
3 post-install runs
Compare the worst pre-install run to the best post-install run. The peak horsepower difference is 20.

There really should be some type of ISO standard for measuring before/after hp gains. Wouldn't that be cool?
That would make it a level playing field for honest manufacturers (such as Tony at Motordyne) to compete and make these numbers usable by the consumer. As it is, most manufacturer's claims mean nothing.
Not all manufacturers are so shady. For instance, Nissan's claims of 6 hp for their NISMO s-tune exhaust has been verified time after time, so I also trust their peak hp claims for their CAI. Peak claims are misleading, however, because they do not include things like throttle response. That is why I bought a Stillen CAI, but I digress. Damn I ramble when I post early in the morning. No more coffee for me.

Except tony @ motordyne....
he compares best baseline to best modded hp...
