Exhaust Pop and power loss

Bare with me fellas...I'm new to this stuff.

I'm getting power loss at about 3000 to 3500 rpm. The car will accelarate and when it hits about 3200 rpm is slows down a little (sputtering I think) and then picks up again at around 4000. (The car slows down like when you lay off the clutch too soon when you accelarate off a light). It's no where near as harsh but it's still noticeable.

I'm also getting a popping sound from the exhaust. I'll get the popping sound when I hit bumpy road. And as the car wines down after reving it up at idle...again the popping sound?

Mods:
AEM SRI
3" turbo back exhaust w/high flow cat.

Could the weather be a factor? Is it the SRI?

could be an exhaust leak causing improper back presure
