I have a turn-out too, and it was too LOUD..... baffled it down on the inlet side.
Took a small 1 3/4 inch pipe piece I bought at Auto-Zone and a Drag Specialties baffle. (Like Diamond Jim used
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1233415444/8#8 ) The pipe fits over the inner header pipe. The small end of the baffle fit in the header. We cut down the baffle so that it was no longer than the pipe (maybe 4 inches) Then welded it in the 1 3/4 pipe. It slips inside the muffler and quites it down.... but if I try I can still set off some car alarms.....
