Loads aftermarket wise.
THS - not overly harsh from what I've read and experienced
BSH - Fairly Harsh so I'm told but no experience of
VWR - Red Robin has these iirc. But they do different types I think Road & Race
VF - I had these in my last car and have a set ready to go on the new one. Not overly harsh and make the car sound like a 6 pot turbo. Slight increase in noise at 70mph but nothing too intrusive. Otherwise you don't notice unless your flooring it.
REVO - Basically re-branded BSH.
