I’m an avid motorcycle rider. I have 5 bikes in my garage. Guess what? All of them have stock pipes except for one, which I bought with the aftermarket pipe already on it lol. I like the sound of my motorcycles exhausts, their already louder than cars from the factory. A lot of people don’t realize all these incredibly loud blast pipes so only that- noise no performance. I have a 21 v7 that I gutted the cats out of for performance, but left the stock baffles on it and it hardly made a noise difference yet I got a noticable gain. Had I bought straight pipes it would be no quicker. And before somebody says loud pipes save lives LOL NO they don’t. Cars won’t hear you till you pass them. Most people hearing ur exhaust are sitting in their house while u drive by. The exhaust points out behind your bike, so no the car in front of you isn’t going to see you because you straight piped ur harley
