I have a 318 pretty stock. It has a 4brl intake 600 edelbrock carb. I am going to put a new exhaust system on the car. I picked out a good set of Dougs headers and was about to get a set of tips. I found a good set in both 2.5 and 2 inch. Should the car use 2 or 2.5 pipe? Does it matter what size I use?
Wanted to ask before I commit to a size.
