Exhaust back fires

Hey everyone. I bought my 08 gt/cs about a month ago and have recently noticed that when I shift from 1st to 2nd it back fires. Was wondering what could cause this????

Aftermarket exhaust? Mine growls in between shifts, hard to explain

Correct me If I am wrong here but a backfire is a result of an incomplete burn, in this case caused by rich condition on hard acceleration under load . You may either have a spark plug or coil that's under performing, and or crappy fuel.

I know what you mean. Gargles is a great word. It rumbles and tumbles as it decelerates for me between shifts.
