That is a fantastic price for an unused full system!
I paid $1430 for mine back in 2008, and that was a closeout price.
MSRP back then was more like $1800.
If anybody here buys that system, I ask that you send me the part numbers for each the components that make up the system.
I lost mine and can't find the parts list since Akrapovic discontinued that system back in 2008 and removed it from their web site.
