Hey All- My first post. Let's see if this contraption works. I have a stock 02 fatboy and am planning to go to an S & S Super E and pipes. I'm undecided about choosing the staggered big shots (with crossover/powerchamber) or a thunderheader. I like the looks of the V & H pipes better and from what i read they deliver better performance than 2 into 2. After reviewing previous threads i get the impression that they are also very loud. I have no problem with louder, but reading "after cruising for an hour my ears were numb" i wonder. which are louder, thunderheader or staggered big shots? Which are better performers? Why do the thunderheader heat shields cost so much, and do you need all three pieces? Sorry for ramblin' I'm writing a book here!
