Hey Guys! Thanks for the banter. Yes it is a log style manifold. It's not as good as an I/R header, but it is a very big improvement over stock manifold. The big hit on a log is #s 1 and 4, the pulse tends to push against each other, but as long as the outgoing is open and freeflowing, it will work nicely. And yes 1992, the higher the horsepower; the less effective. At what level this becomes evident I don't know. Hopefully it won't become an issue at the power levels I want to reach. Gus
