Two cents coming at you..
As you already know about Corsa systems, their claim to fame is not only the sweet exhaust note but, it's attention to absolute negligible interior noise resonance, attention to detail in welds, mirror polish stainless tips, (thick and jewel-like)overall attention to deatil in their workmanship. Not to mention customer service, how accessible are they to reach on the toll free, not just the middle man who sold them to you.
I've heard the Boats and they do, sound nice. I'd like to hear from Billy Boat fans about any interior noise drone at cruising speeds.
If the Billy Boat system has gotten the interior noise resonance to a liveable level (this you must know before you buy, very important..you'll hate them otherwise noise it gets old). Conversation should be at normal levels and you can enjoy your sound system (that is, when you're not wanting to enjoy the sweet sound of the exhaust note).
Let us all know what you decide.
