Is the Kolak 3" exhaust the correct size for a 4.0, or would the 2.5" be more appropriate. Probably do this with the stock exhaust manifold for now, as it is new. When the time comes to replace it, something better will go in, but for now (read $$$) I think I'll just improve the cat-back part of the system.

Any opinions or anyone done this?

I have heard that 2.5 is optimal for the 4.0..

But I have also heard good things about Kolaks stuff..

does that serve to confuse you more??
