i recently replaced the resonator pipe with a 3" sraight pipe. A few hours after installing the pipe i started hearing a squeeking sound from under the car. I also noticed water leaking from the bracket that connects to the axle-back. does anyone know what it might be? I haven't had the chance to look raise the car and take a thorough look under the it.

 

update: while driving today i noticed that the squeeking sound same whenever i step on the gas while letting off the clutch. I don't think it has something to do with my exhaust. the sound is coming from the engine..... i think.
