    Haven't seen them or heard them, but am totally skeptical about those bogus HP gain results. They are measuring the benefit of upsizing the headers on a 408 c.i. (6.6L) engine, not a 327 c.i. (5.3L) engine. Why didn't they just compare stock 5.3 manifolds to the 1 3/4" headers and the 1 7/8" headers???? When I see stuff like that, I just turn the page, and fugettaboutit, until I see better info.
