I have the ultimate 3 piece seat also, best thing since sliced bread. Ok, I never had bread that was'nt sliced. I'm a vance&hines fan, both my Strat and Warrior have them. The 2 into 1 on Strat is the sweetest sound, not too loud and plenty of rumble. My Warrior has 2 into 2, much louder but still acceptable. My wife has had the occasional cell phone calls while on the road with no complaints. Oh yeah, don't forget about the improved power of 2 into 1 with no EXUP.
