HEy everyone, I haver a RS4 RTR and i just bought a Yokomo tuned pipe for it. It came along with this really really tiny screw and the dealer handed me a wire. Now how am i suppose to install this? I know i need to remove the old muffler but now how am i suppose to secure this new pipe onto the chasis with it just being connected to the engine and a wire, which i have no clue on how to secure it. Oh... also for some reason, the dealer took some pliers and he bended the end of the wire intoa loop. So if anyone can be kind to help explain how i would go upon to install this, please tell me how. thank you.....I appreciate it.
