What Made "Old School" Restrictor Plate NASCAR Sound So Great? (Back to Back Sound Comparisons)

I have spent the last few months doing research and collecting firsthand information on these things to find out exactly what the deal is. I know there is all kinds of misinformation out there on this subject... this video will clear the air with information from the guys who built the exhausts. I also show back to back sound comparisons from numerous generations of nascar along with iroc cars and my own personal Escalade. Hit that subscribe button if you're an exhaust nerd too!
