Hmm that question is kinda like asking what chick has the best rack etc. Everyone will have a different answer

Anyhoo here's my 0.02

Since your car is "mostly stock" I would stick with a 2.25 or 2.5" exhaust. Bigger isn't always better, the 3" pipes would hurt your torque and maybe your overall performance as well. Many Big block Chevys run pretty hard with 2.5" pipes on the street.

For strict high horsepower racing etc, especially with 347 or more cubes the 3" pipes will let you breathe better at high RPMS
