weird cackle in 5 inch straight pipe

powerstroker97 · 06-15-2012, 04:47 AM

Just took off my magnaflow muffler and replaced it with a 5 inch delete pipe. Sounds good except mid range heavy throttle it get a high pitched cackle to it, almost like a chevy 350 gasser with small pipes. Cant figure out why its doing it so any ideas would be appreciated,

As long as it is running correctly I would not worry to much about it. But thats just me.
