My favorite thing about my max and the full race UFO exhaust is that when I pull up next to any HD.... They stare.... Look at rear of bike... And if they make eye contact with me the look straight down. They don't Rev their pipes at all. They usually just turn off and slowly go down the road shifting at 1500 rpm lol.
When I was in Jamestown couple months back.. All the Harley's were constantly revving their bikes. When I started up my vmax they just stared and started talking to each other and got closer to my bike. I didn't have to Rev it or draw attention.... They knew it was something different. People can't hardly believe when I tell them it's pretty much stock with air filters, jetted carbs, and exhaust (stock cams etc).
Buddy on a Road Star was cruising with me and his bike sound great Bubs Rinehart long shots.... When he was behind me and I whacked in 2nd and 3rd gear he just giggles and said he is looking around the area for a 1970 Chevelle with big meats on the back because my bike sounds more like a race car than a bike.
Every time I pull into a parkinglot, bike show, etc... People just stare and walk over.
