Sv6 ute gets louder after stalling??

[zepherrrrr]

Gday folks,
so recently i have discovered that after stalling my sv6, turning her over again and driving off, she gets louder than a priest on a sunday.
i have no idea what causes this but it sounds sick (nice and loud) for a while then goes back to normal..
i have the stock exhaust with no mods and a ss inductions growler on the front..
any ideas as to why this is happening and how to keep it loud, other than deliberately stalling it at every set of lights??
cheers guys.

If you exhaust note gets louder then your muffler might be the culprit. Collapsed/baffles broken away; flexible joint broken or cracked; exhaust pipe flange gaskets

If the induction noise increases then the air intake ductwork might be separating.
