Dumping exhaust down under the car

[famous bob]

how it sounds or if it drones, depends on the motor, gears and rest of the exhaust. my 74' is otherwise bone stock and sounds fine at any speed

For you doubters , run with a full rear exit exhaust , then pull them off and dump them, u can actually feel the diff in power . I had full 3" turn downs , and had the rear exit exhaust added/ built for a 406sbc chevy I built in a 92GMC shortbed , I could tell the diff when I started it and backed out of the muffler shop, drove straight home and pulled them off and reinstalled the turn downs.
They are still laying in my shed if anyone wants them , over the axle tail pipes , exit out the side like a z 28 ,shortbed standard cab GM ----just pay shipping !
