I just installed my new TurboBack Agency Power System. I sounds amazing but, but after a few days i have noticed that there is a loud clicking sound only in idle. I went under it yesterday to tightin all the bolts, but still loud annoying sound. Its pretty obvious that it is an exhaust leak i just dont know where it could be. Any advice i would greatly appreciate it. thank you.

 

My speedcircuit did that with in the first few days also, After I hit a puddel. It went away and haven't had a problem since

 

make sure you dont have some of the old clips that held the O2 wires rattling against it, mine did that, sounded like it was under the shifter. Had to crawl under there and do some bending.
