Hollow Thrush Mufflers (vintage?)
On a side note I had a 70 coronet R/T 440 six pack back around 1979 and it had two of the thrush mufflers which exited in front of the rear tires.
Had a neighbor who was about 8 years older than me and was a sadistic bully to me all the time when I was younger.
He bought a house around the corner from his dads and it was on my route home , there were other ways home but this was the most direct.
He had a large picture window in his front room .
So one day he comes over while I working on the car and says that picture window is getting vibrated by my cars exhaust when I drive by and could I not come that way home.
I didn't drive by his house to rattle his window on purpose and hadn't even thought about it.
Well after remembering him being a sadist bully to me years earlier I made it a point to drive by his house as much as possible with the car in low gear at round 5000 rpm.
Felt good to pay him back
