Some great wall papers over at Hemmings... especially if you trim off the logo This also is a great photo of the factory cast iron headers on the 426 Max Wedge. It probably never was better from other manufacturers when it came to exhaust speed parts, Mopar made these and fitted the max wedge and hemi cars with optional open header cutouts. I don't think I've heard of any other manufacturers factory exhaust race parts that were better.
