wat up. I just bought a 1992 550sx! I love it. I rode my friends 87 550 one time and it got me hooked!! I bought my ski a week after my first ride. I have taken it out almost every day since I got it. My 550 is stock and very clean only a few little scratches. The bottom is very clean no scratches!!!! Im ready to go faster and higher!!! Wat should I do first to get the most power out of it???? I no I want to get a pipe but what kind should I get?? I need help I don’t know where to start!!!!!!
