My exhaust valve failed on me so I plugged the vacuum line and now it does it on shifts from 3 to 2, and 2 to 1 every single time continually until the rpms drop back down to idle. Love this sound. I even get a massive popping sound in between every upshift on heavier acceleration. Sometimes the upshift pop is scary loud.

with my PE, holding gear @ 3000rpm and slowly let go on the throttle, the "pop" is the head-turner for sure. drive it next to a wall, it sounds like a small firecracker, hahahahahahahaha
