I can't speak for everybody else, but I can tell you why I don't do what I think you probably mean to say, which is "tuned headers". I spent a really inordinate amount of time building a set of 321 stainless headers, put $400 in material alone, and it took me almost forever to do it. Stainless is tough stuff! Mild steel would have been easier (and apparently lasts just about as long), but even so, all those bends and extra welds would have tripled the effort. And....there's simply not enough room. The simple straight exhaust I made is just absolutely all that will fit under my engine cowling, and anything more would have cost another couple of inches, not to mention a few more pounds, megabucks more in material, and triple the time. And five percent more power only buys you a very few miles per hour for the effort. Attention paid to aerodynamic details would likely pay far more dividends (not that I've taken advantage of those either!). I hope y'all understand why I "slack" much of the time, and there's often a pretty good reason...
