i dunno if its the clutch or what...like i can take off normal sometimes but other times i hafta give it more gas to get a normal take off instead my motor shuddering (es inserts) when the rpms get too low. it seems like the clutch is going out but sometimes it feels ok. also, when i take off sometimes i get little exhaust shudders (i have an exhaust leak) and it kinda pop pop pop's when i take off...will a new exhaust fix that?
