We had customers with Mind Train that live in gated communities and uppide uppide 'exclusive' neighborhoods ( Jorge Bacardi is one) that got a ticket for noise! On WILLIAMS ISLAND no less, one of the highest priced zip codes in America, speed limit 30 mph! We had to quiet his '72 down.
That exhaust sound is to die for OMG everyone that hears that sound when we start a car here at the Pantera shop, wants that system. Problem was back in the day as they say, those inserts made 'em too quiet. Removing them? Don't even go there. They reusted in.
