As far as looks go ... I voted with my wallet already . COMP WERKS
That said the Only other pipe I would choose is the SC low pipe .
I don't think there is a low pipe out there that is going to make the Speed sound like a sewing machine , and the SC has the baffle to give you options .
The scorpion looks nice too , but with the comp werkes you need not remove the pipe to remove the rear wheel . Time saver .
