with the HRC end cap the tube is gone....its just the end cap with a screen type spark arrester, and yes the opening is way better, I have one on mine and its way better, and sounds mean.Originally posted by tuffguy@Apr 8 2004, 10:07 PM
Where I ride I also need the spark- arestor. On the HRC endcap isn't the tube that comes off the sparky a much larger diameter. Something like 15/16" to 1 5/8"?
