I picked up a set of 2 into 1 Patriot Defenders several months ago for $400. The performance is good and they have a Butterfly baffle in them that is cable activated. I can change the DB level from pretty loud to stock while I am riding. I mounted the cable lever behind the rear shock air cover so I could reach it. The only problem I have had with them is the 02 sensor plugs blew out as they weren't torqued tight from the factory. I just picked up a replacement pair at Napa and ordered a cheap back up pair just in case it happens again. It may not be the look and sound you are looking for but I am happy so far - Bob

Watch out with these in Peoples Republic of Kalifornia, any exhaust with valves that can be opened by the operator can get you an instant citation.
