Roughly 30 years ago when I had my Cico equiped 3CL/Jota brand new, it had the Cico full fairing in blue with a white stripe and a 3-1 megaphone exhaust on it. I was re-fueling the bike, whent to the cashier to pay and returned to my bike, when 2 Harleys with moderately loud exhausts came to the gas station. They jumped off the bike, looking around like they were the king of the roads, obviously very proud of their bikes. I said "hello" to them from a distance, which gave me just a slight noding of their heads as a return.
Put my helmet and gloves on, turned the key and pressed the starter button. Bike barked into live and the whole ground was shaking. Was fun to watch their jaws droping almost to the ground, eyes wide open, looking quite shoked to the bones. Everyone having ridden a bike with a 3-1 Megaphone exhaust knows that feeling... Big fun...
2 days later, I wanted to buy some stuff at the Cologne branch of "Louis", the bike parts shop. I had to take the bike with me as I needed to check if things fit (not sure anymore what it was actually I was looking for). I used the highway to the south of Cologne and rode up the "Bonner Strasse" from the highway exit to the Louis shop, when I actually noticed a group of cops checking out bikes. There were a bunch of Harleys already parked on the side and examined by the cops. One cop with a lolypop (you know this sticks with the "Stop" sign on it) looked my way, steped onto the road but was obviously unsure what this really is that was thundering up the street towards him. He looked to his colleagues, exchanged some words and while I had shifted up to the 4th gear to just role along in idle, he looked at me again, lifted his shoulders as to "I don't really know what to do" when I passed him. I saluted him and his comrades with my left hand. He actually was so confused, he saluted back and let me pass without examination of my bike
Roughly 90 minutes later when I came back the same way after successfully spending money at the Louis store, they were already gone. Not sure I would have gotten away with the fact that the exhaust actually was in the papers of the bike. Today, they would defenitely stop me, take the exhaust off the bike for analysing and with that, leave me with a bike without exhaust, which I can not ride, so I'd have to get me a transportation back home for me and my ride...
Just to be clear: sound is good, but these 3-1 megaphone exhausts are an assault to the ears and body of everyone passing or beeing passed! Would never ever mount one again on one of my bikes. The "Jota" cans are already to loud I feel for every day usage.
