So last night I was driving on the highway, just entered from a ramp, and felt like driving hard. Mad sure all temps were at normal before I dropped gears...they were...I did. I stepped on it in 2nd and around 6000RPM I felt a loss in power and heard POP POP. I was like WTF. So then I shifted into 3rd, gave it gas started boosting and again around 6000RPM it poped and I felt a loss in power.

Any idea what this might be?

Thanks guys
