AS YOU CAN SEE FROM THE PICTURE THE INSIDE OF THE BAFFLE IS FLUTED TO REDIRECT THE GRUNT. THESE BAFFLES ARE 23CM LONG BUT THEY CAN BE CUT DOWN TO SIZE TO FIT IN THE SILENCER. EASY TO INSTALL TO MAKE YOUR VERY LOUD SPORTS CAN’S SOUND QUIET FOR THE M.O.T THEN WHEN YOU GET OUT JUST TAKE THEM OUT AND AWAY YOU GO AGAIN WITH THE LOUD GRUNTING NOISE AGAIN NO NEED TO CHANGE YOUR CAN FOR THE M.O.T ANY MORE!
