My truck needs a complete exhaust from the manifold back, so I was thinking it would be a good time for headers. Is the expense worth putting them on? Do they really make a big difference in driveability, even with a stock intake? Headman makes a set that is reasonable $180, and it has dual outlets for dual exhaust.......will it sound "ratty" with duals and a nice set of mellow mufflers? Anyone running them?
