360 la headers & straight pipe

My one time at Band Camp story.
12.3 to 1 340 large cam open headers 16 inches pipe. Towed to car show at a place that serves adult drinks and has bikers.
So sat all day, I went to get truck-trailer parked on side street.
My wife as I pull up starts car up. A lady with 2 of her friends jumps like she was shot out a cannon. I look and see she tossed her drink and her pants are wet.
I tell my buddy who knows her ask what she was drinking so I can buy her another. He says my wife already asked and that's not drink on her pants!
That cars loud and loopey
