Pros
Excellent sound absorption and reduced backpressure for improved engine performance.
Cons
May produce a louder exhaust note than desired for some drivers.
I mounted them on my 72 Nova with an 11:1 SBC 406 that goes up to 6500 rpm. At idle and while driving, they sound harsh and deep, but not unpleasant. At wot they will let the engine breathe freely and wake the dead. :-D
