Anyone running 3 inch exhaust piping on their 5.7? Can anyone tell me the pros & cons of running a 3 inch exhaust?
They run open headers because they can expell the gasses quicker. Pipes to big slow the velocity so it takes longer for the gases to be pushed out. Street legal cars cant have side exhaust or open headers so you need to design one that will run the length of the car and get the gasses out ASAP.If your theory held up, then why do drag cars run open headers? Less restriction you have the better...
