Full Exhaust help

[DuctheMonster]

I'm looking for a full exhaust system for my 07 s4r testastretta that will give it that almost...Harley sound that deep throaty sound that comes from the L-twin. Does anyone have any suggestions? I have looked into the motocreations boomtube and some other exhausts. Price is also a factor so if you have suggestions please maybe give a base price that they would run. Thanks

I started a 1000DS at the shop last year with full Arrows installed, and I was pretty damn impressed.  Boom tubes will probably get you closer to that Harley sound just because it's more of a hollow clacking than a low rumble.

Sweet, I have looked into arrow and boomtubes and those are pretty much the two I'm debating between. The only thing with the boomtubes is that I have heard that they are not super great for your bike and kill a lot of power...does anyone now for a fact that this is true?
