Gargle sounde when I let off the gas with my RNR 3" turbo back

[GSXpower]

this only happens when I am at low RPM driving around town, when I let off the gas to shift or stop, the exhaust makes this wierd gargle, burbling noise if that makes any sense. It dosen't soud like a backfire, but maybe that is just something that large exhausts do.... what do you guys think?

maybe there is a leak between the flanges

my 3" turbo back does the same thing,

That seems perfectly normal w/ a big exhaust to me.

 

[markGSX]

thanks man

Yeah I supose that normally the stock exhaust would muffle that sound, but when you can see straight through the muffler that is why every sound comes through I bet. Thanks

That noise is is the sound of the just combusted air/fuel mix in the cylinder as the exhaust valve opens. You can hear it because the exhaust is so free flowing that the pulse from that cylinder goes straight out the pipe without any interference (from the other cylinders) Pretty cool when you think about it.

Mine does it as well (Apexi N1) . . . and I just figured out today that if I drive around the interstate for a while in the upper RPMs (4k+) and get everything good and warm . . . when I push in the clutch JUST long enough to shift, it'll backfire/pop . . .
