I know you posted this to market it instead of to gauge the market, and everyone is giving wants/wishes/desires. I guess I'll find myself in that camp though, and the population is showing how to define your niche -- make it controllable by the aux switches (all of my homelinks are taken up already), make it a 3 position valve, and warranty the actuator for a decent amount of time. I would pay a significant sum of money for a great sounding exhaust, regardless of brand, if these things existed which is why I haven't moved off my SLPs yet.
