Wouldnt the 3" downpipe give better performance??? I assumed that this would be the case since the stock exhaust is 2.5
As i stated before i dont really care about price but cheaper would be better. I was leaning towards the zzp as the S&S ones will run me about the same price. Now that you told me the S&S headers are 2.5" im not sure i want to get those now.
