I do all the time when cruising, that's how you get reasonable gas mileage... this car has more than enough torque to be driveable down to 1400rpms when cruising around. 60mph in 6th is only a bit over 2000rpms IIRC. The stock exhaust does not drone at these rpms, so I am completely confident it is possible to design an exhaust that does not. That being said the drone might not be loud enough to make it worth the bother.
Exhaust sounds nice in the higher rpms, a bit rattly down low/idle. Excited to hear more from the freeway at 65mph with DPs.
