exhaust sounds, looks really good specially the black. the matt black finish is excellent. baffles can really easily be taken out. the original buffles are annoyingly loud (to me at least) so wrap it w/ fiberglass or you can also use v&h quiet baffles or one of the cobra quiet baffles and that should give a nice balance. yes save your ear! this exhaust really looks good on harleys dark customs as it has a low profile look. everyone runs v&h pipes but if you wanna be different this is a good option.

I would recommend this item to a friend.

THE PURFACT REPLACEMENT PIPE FOR DYNA

March 1, 2011

FOR STARTERS THE INSTRUCTIONS NEED TO BE WRITTEN IN CRAYON IF YOU EXPECT A DEALER TO INSTALL. I READ REVIEWS WHERE PEOPLE AND DEALERS HAD TROUBLE INSTALLING THESE PIPES AND I THOUGHT IT WAS A FLUKE SEEING THAT SUPERTRAPPS REPUTATION IS OUTSTANDING. I WORK ON MY STUFF BUT SEEING I PUT THESE ON A CVO I WANTED THE DEALER TO DO IT SO IT WOULD BE DONE RIGHT, WRONG MOVE. THE DEALER COULD NOT GET THESE PIPES ON. SO I TOOK THEM HOME AND IN 2 HOURS HAD THEM INSTALLED MYSELF. THE KEY IS "FOLLOW THE INSTUCTIONS AND USE COMMON SENSE AND YOU CAN GET THEM RIGHT. WOULD ADVISE GETTING A 1/4 INCH LONGER BOLT THAN SUPPLIED FOR THE LOWER MOUNT BOLT. NOW THE GOOD NEWS .... MADE MY CVO COME TO LIFE. SOUNDS LIKE A HARLEY NOW AND RUNS LIKE A 110 INCH SHOULD. LOOKS GREAT AMD SOUNDS LIKE A MEAN MOTHER WITH BAFFLES LEFT IN. GOOD FIT AND NICE FINISH. BUT TAKE YOUR TIME. P.S. THE STUD WHERE THE LOWER MOUNT HOLE IS HAS TO BE REMOVED AND THE SPACERS MUST BE USED, THIS MAKES THE MOUNTING BRACKET SITTING AT A BIT OF AN ANGLE THE BOTTOM OUT MORE THAN THE TOP, THIS IS THE WAY IT NEEDS TO BE !!!!! LITTLE TRICKY BUT WORTH THE EFFORT

I would recommend this item to a friend.
