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"
