Put the expansion chamber exhaust and its slower
Put on the expansion chamber exhaust and its actually slowed my bike down, and its sounds crappier too. I had a stock exhaust on it, with the cap off, stuffed with steel brillow pads and it sounded great and ran great, really torque and had good top end. After putting the expansion chamber on, it sounds worse and I feel like I lost that torque, but the top speed seems around the same. Has this happened with anyone else??
