Decel Exhaust pop ??

I have noticed my SS/M6/LS3 has Decel exhaust noise (gurgle/pop) while in 2nd or 3rd gear and off the gas-pedal slowing down (2000-1300 rpm) while coming to a stop.
Is this normal? Just curious, thanks for any input.

Yes it is normal, most manual cars gurgle and pop when decelerating while the transmission is moving faster than the engine. nothing to worry about. V8's are especially known for this and everyone i know loves it

A good quality exhaust X-pipe usually helps eliminate most of the noise. If you do a CAT-back like the one made by Magnaflow, it has a X-pipe built in as part of the package. Good Luck
