+1 for the AE exhaust coupled with catless DPs - I love the sound - although it's deepest on a cold start - drones from 1.6k-2k RPMs ish - which is pretty similar range from the stock exhaust drone so I am assuming it's not an exhaust specific issue.
I am planning on recording the sound from cold start on to some warm gear pulls and I can post the link here when it's finished so you can compare before you buy,
