HKS jobbies sound pretty similar.
You lose the hard-edged lawnmower sound, but I think that has to go the moment that you go for anything remotely effiecient Same as porting the standard things - the air is no longer banging about, wasting energy making the funky boxer beat
Presumably there are other out there that do the same. The now-unavailable MRT ones also retain it to an extent.
