In a few weeks I will be buying some stainless headers,high flow cats, and "y" pipe, it's the whole setup stainless from Dynatech,I already have a cat-back exhaust,where do you think is the best place to get a great price on this, I have seen it run about $1,300.00.....I have a 2000 F-150 4x4 e/c,short-bed with the 4.6, thanks guys for the help.
