Compared to the stock metal only baffles these V-Twin 10″ long baffles with fiberglass packing lowered the db level marginally but changed the frequency to a more bass and pleasant sound. To fit in the muffler about 1/4" had to be trimmed (ground) off the inside end of the baffle due to the mounting location alignment with the muffler's stock mounting hole location.
Too quiet and restrictive for my taste.
these slipped right in to my ulltima big growls. appear to be well made. took the db down lots, left with just a nice thump thump. won't wake up the neigibors babies no more. ) :. wife seems happy ) :.ultima big growls+these=costs effective set up!
great quality , fit inside my drag pipes perfect
Outside diameter is 2-1/4. Inside diameter is 1-1/4. Nice product, but the inside diameter was too small for my application. My header tubes are 1-3/4, so there is no way I can get decent flow from a 1-1/4 inch exit pipe.
they are okay but they need to be a bit longer like 16" instead of 10"
