Just about 10 minutes ago i was pulling out of the local speed shop. The speed limit is 55, so i had to get on it pretty good to keep pace. When i shifted into 2nd it felt like there was a little bit of a power loss. And, the exhaust sounds funny. It kind of sounds like a helicopter in the distance. Also, the exhaust is vibrating alot, and shaking more then usual. This sucks. Anyone know what is wrong? thank you in advance.
