I have a Base model. The stock exhaust had some drone and the tone was too high for me. I currently have ER Hi-Flow Cats and a full 3.5in cat-back AA Signature Kit. Now the sound is deep, loud with valves open, and sounds wicked racey-good. With this setup I still get 1 or 2 natural burbles even with BM3 burbles turned off...its so cool. Sounds "real".
