Got way to excited about bigs gains on the first dyno day, assumed those were true and did not re-test, produced a massive batch and sold them based on the bogus results. The dyno, which had parameters that could be changed, was not configured correctly. Specifically Dyno Dynamics units need to be gearing calibrated each run or use previous inputs. This is why Dynojets are the gold standard, the results are the results. Unless you mess with the weather station you are going to get largely the same results elsewhere.

0 emission testing exists where I live.

Yeah - numerous states (or parts of states) in the US have no emissions testing or requirements.

That only adds to the oddity of this dyno. The shopped uses Dynojet. I prefer SAE correction factors to the STD correction used personally as it reads more consistent and conservative.

The correction factor accounts for weather conditions so the 205whp+ at 60F shouldn't become 190 even at 90F. Unless they have the correction factor disabled.

All states have requirements it is Federal law. Some States just chose not to enforce it.

[Dake]

But in the absence of enforcement (or even testing), there are effectively no requirements in those states.

Yup. The Feds don't enforce those laws at all - the FBI aren't running around pulling people over to check they have proper exhaust. They have, uh, "better" things to do.

And the local police don't really care in the slightest what Federal law says, generally. Their job is to enforce local laws. If there's no local law against it and they want to be jerks, sure, they could cause trouble but it's probably a lot of paperwork to try to get the Feds involved to actually make the charges go anywhere.

So the net result is that (like most laws regarding marijuana) local law is the only law that gets enforced. If there's no local law, it's effectively legal.

Yep!

I live in Alberta, and there is no legislation here requiring a catalytic converted at all.

Yes there is. You have the same federal requirements as the rest of the country. It again comes down to the fact that there is nobody that enforces those requirements there. That does not mean that there is no law.

This article says there is no such law provincially. It's confusing why a federal law can be ignored in some places and not others. That makes very little sense. Didn't think provinces could pick and choose what laws they like or don't like that are federally mandated.

Either way, seems much easier to fit catless headers in AB compared to Ont.

Because federal agencies are who sets the emission/safety regs on what can be imported and sold. After that it is up to provincial gov to enforce.

His wording is a bit off I think. There most certainly is a requirement to have them and they could fail inspection even in Alberta depending upon how far the inspector goes. The same goes for every other piece of emissions control equipment on an engine. The federal law applies everywhere and the province can't over rule it. Alberta just never bothered with their own (why would they say the same thing really?) so it seems like a loophole but really isn't.

Meh easy here too. Although there are Provincial as well as Federal rules it once again comes down to nobody really enforces it. Ontario has even dropped the emissions testing so it is even easier to get away with it now.
Most that get dinged for exhaust here get hit for noise not cat removal. Pretty sure the same applies there.

Or the municipal gov if they want to do so. Any lesser level government can make rules that are more stringent (some cites have stupid heavy exhaust noise bylaws) but the Federal remains the minimum standard. The federal not only says it has to be sold with cats but they must remain intact and "not tampered with".
When they ever reach a level where anybody actually wants to enforce that rule it could be interesting.
