@mattlqx I saw this on your FB page. What's the scoop on this? Did you try it on track and did it work?

Just a word of caution...I saw a Corvette (ZR1 I believe) plug his exhaust to pass sound check on the last track day I attended. The heat under the rear valance melted the resin and the back end caught on fire mid way through this run. The guy pulled to the middle of the track and the emergency crews put it out quick, but it was scary looking. Car was messed up bad.
