Exhaust Popping Sound

Good one brother!
Teach the youngin's how to blow their mufflers apart (the one's drivin' old carbureted stuff)...Oh and it helps pumping the **** outta the pedal while you're at it!

All kidding aside, one of my buddies just got pulled over doing it in his old D350...

If yer lookin' for all that poppity pop pop on trailing throttle, that's a combination of exhaust system (like the the glasspacks) and maybe a header leak allowing some fresh air into the exhaust, or an excessively lean condition when you chop the throttle, causing it ( the lean condition causes a mixture that either doesn't ignite in the combustion chamber or only partially burns, then re-ignites in the exhaust).
