New 2015 Roush exhaust tunable with your iPhone
I just read about the new Stage 3 Roush Mustang, and the most interesting thing about it is that their new exhaust is adjustable as to when it is open and when it is closed.
Roush has something that plugs into your OBD II port, and you adjust the exhaust via your iPhone.
Want the Roush rowdy up to 60 mph, then quiet on the freeway with NO drone? Just dial up those settings, and you have it! This sounds like the way to go to have fun around town, and not have the exhaust drill a hole in the back of your head at a constant 1,900 rpm.
Other exhaust makers will have to follow suit, I think......
