If you are talking about an occasional snap, crackle, pop on decel..........its the nature of the beast.....
Anything else....I would be concerned.

Mine does that, but only when I accel Sounds real sweeeet when I'm shifting into 2nd and 3rd; a nice, deep burble. Started doing that after I installed the Borla cat-back.

Only when I get on it first thing in the morning. Just a reminder that I shouldn't be revving past 4K when I just start the car up on a cold morning.

Yea I get it all the time and its even Louder now because I did a muffler delete, i've been hearing it's the center resonator that people have swapped to an X Pipe that solved it, I think it would be a combination of that and a cam swap should hopefully do the trick

Yeah, the stock cam in these things seem to be a large part of it.
Mine was something terrible on decel or downshift with the headers/exhaust and stock cam. After cam swap I rarely get any boom, pop, bang.
