Hey guys, within the past 2 weeks, i installed BC racing coilovers, spc rear camber kit, and invidia q300 catback. the catback was the most recent mod (3 days ago), and ever since then, I'm noticing a ridiculously annoying squeaking noise. It sounds like an old kia thats about to **** the bed (no offense to any prior/current kia owners). Im assuming its the exhaust because, although it is not constant, I can sometimes hear it when the car is not moving and if I rev the engine a little bit. I will try to take a sound clip when my ridiculous schedule allows me to. Today i quickly got under the car and noticed that the 2 hangers towards the middle of the exhaust were not hung properly (probably due to rushing the night before the Uconn car show this past sunday). Not sure if that will make a difference but just thought id provide as much info as possible. If anyone has any insight, please let me know. Thanks!

 

 

soo for those that happen to stumble across this (lol), i took my foot and gently tried moving both sides of the exhaust and its definitely the left side that is making the noise. a friend of mine suggested polyurethane hangers. anyone have any input?
