Finally put away the funds for new pipes for my F6. Tried the Cobras on a friends bike last week and didn't like the sound at cruising speed. Did like the sound clip on the Bassani pipes but a lot getting said about the different size gaps on both pipes. Is it that bad? What other options might you recommend. I ride 50% with an open face helmet and 50% with no helmet. It has to be real cold for me to put on the full face coverage (that's 40s here in Florida). I want to purchase ASAP. Tax refund is in. Thanks in advanced and I enjoy reading this forum.
