Exhaust Snap and Pop

[jaykay]

I am getting some snaps and pops when blipping the throttle for down shifts. It sounds great but I am wondering if this an indication of problem such as lean condition or it's simply a function of my bypass exhaust and 2nd cat delete pipes; softronic flash; 74 mm tb.

Its not an out and out back fire but a....pop! Snap! I realize that I am using exhaust noise as feedback for throttle blips.....the snap crackle pop catches me out such that my engine speed is not spot on when let out the clutch

Anyway thoughts?....durametric scan is clean
