They are KYB's I checked them and that is the name on the struts.
The noise is most noticable when accelerating from a stop or low speed when braking gently. I always thought of it more as a groan, but I guess popping would be another way to describe it.

Is it actually a popping sound? The noise I've heard about is a distinct sound like a pop when accelerating. Some have complained it sounds almost like a thump and even a pinging metallic sound or resonance. It will be felt in the steering.
When you had the KYBs installed did you install new coil spring cushions and an upper strut mount which has the load bearing? At 125K miles that should have been replaced. The signs are more like a groaning or creaking sound.
One step I noticed on strut installs is the failure to replace the upper strut mount or cushions. What I do if they appear to be OK visually is coat all metal to rubber contacts points in the strut assembly with polyurethane bushing grease. I apply liberal amounts to the load bearing. The same stuff used for stabilizer bar bushings. It is silicone based and waterproof. In the pic below the coil spring cushion and upper strut mount/bearing are coated with the special grease. This was a recent strut install in my wife's '99 Regal LS using Gabriel Ultra G-Force struts. The DIY install went smoothly and no problems noted afterwards. No noises but restored ride and handling like when new.
