So I had the chance to line up with someone who installed loops on his B. I have Guhl reflash, K&N drop in, and Torq master King Snake exhaust, he has the loops only. I've been debating on the loops for 2 years now, I have no drone I was just hoping to get more exhaust rumble and a little more power. I ate him up off the line, perhaps the loops drop some performance on the bottom end????? I got out on him at least 2 bikes from the line twice, I kept that gap all the way up to 120 when we shut down. Rider experience or the loops????? I'm not sure to be honest, the guy's been riding for a while and knows what he's doing. Since I have no drone this was the determining factor on the loops for me. Just an fyi post....not trying to stir the pot one way or another.
