Well since i've gotten my custom turbo back exhaust, my car continues to make this wierd fluttering/farting/rattling/clicking noise when i let off the gas. The system is turboback with 2.5" piping, a glasspack, and a rear magnaflow muffler with dual tips. It only makes this strange noise when i let off the gas after punching it. the exhaust gets somewhat louder after i let off the gas when it makes this higher pitched strange noise. I'm pretty sure I dont have any exhaust leaks but am not %100 positive. this noise has been the same for more than a year and has not gotten louder.

Anyone have any ideas of what this could be?
