The problem that aftermarket exhaust makers face is that the US EPA requires that the exhuast be tested for the exact model of the bike. On the OEM there's an embossed stamp stating that it meets the EPA specs for loudness for the KLR year range. So unless the exhaust makers want to submt an exhaust for each model and pay to have it tested they just get around it by stating it's not legal for street use. Notice that in magazine ads the aftermarket guys don't show a street legal bike!
BTW Harley sells their own replacement exhausts that they get EPA certifed. Of course there are still the louder aftermarket ones that all the pirates run (if they aren't running straight pipes, arghh).
There's a federal law regarding exhaust noise levels and communities are using that to crack down on loud bikes. California (my state) passed a law that basically states that if the exhaust doesn't have the EPA label it's illegal, doesn't matter if it's quiet or not.
