I have a 454 with a Comp Magnum 550 lift/236@.050 duration cam, headers of unknown brand, and 2.5" pipes back to Flowmasters. From there I think it goes to 2.25" pipes and into 4" chambered extensions out the back. No X or H pipe. I love the way it sounds. The headers are not "shorties" and have either 1-5/8" or 1-3/4" primaries which I consider to be a little small for my application. I have both a 1 meg and a 5 meg movie of it either of which I'll email to you if you'd like to listen.
