HL is selling just the duel port cover for $18 on ebay. Will that bolt up to a stock 660 muffler?

Yes

Installed my stihl dual port muffler....sounds great. It even scares my neighbors Doberman dog off...and he normally barks at everything that moves. Picked it up from a dealer in a rural area for only $26!
