For my 2010 SG I also did a Stage 2 at delivery and had the dealer install Nightstick slip on and a download for the ECM, which improved the sound, but it isn't what I really want. When you kick it hard the sound goes high rather than rumble like a Harley should. If I did want to invest the 1K into it, V&H has always preformed well and looked great. But if I wanted to stay with the 2 into 1, I have read that the RineHart 2 into 1 has great performance and the deep sound that I am looking for in a muffler system.

Anyone have experience with any other 2 into 1, or should we go back to a true dual system like HD seems to be doing?
