I've been considering a more aggressive switchable system for a while. Does this use the PSE button? It would really be in their best interest to have some sound clips. Dropping $3k + install only to find out it's not what you want probably limits the sales numbers on this system. Maybe the reason they don't is because the sound doesn't justify the cost?
Certainly understand, if I were making exhausts, I wouldn't build something if I didn't have video/sound clips. Not sure why they don't have that content available. That being said, all of their other exhausts sound good, I imagine this will fit in fairly well in terms of balancing valves open/closed like some other aftermarket companies. If you have PSE it will work with the factory button, if not, there is a remote control. I'm trying to give someone a really good deal due to the "risk" of not hearing it before buying. I can't imagine it would sound bad.
Essentially all this does is smooth out the mid-pipe and provide less baffled mufflers over stock. Probably worth a few HP and I'm assuming about 15% more noise with the valves closed and then awaking the animal with the valves open.
If I had a Macan, I would try it myself, but I no longer have one. If anyone is interested, let me know. I don't mean to shove it down anyone's throat but can get some very attractive pricing right now if someone is in the market for a system.
