I have a set of the #5204 headers on my Dart Sport. No plug wires problems, no ground clearence issues. You cannot run power steering with these headers. the #1 tube will hit the p/steering box. The fit is good, the steering center link has to come apart for both sides to go in. as for performance, I upgraded my whole powertrain pkg. I have ran them with a 3" pipe & crossover, & ultra-flo mufflers, with a open exhaust & 12" collector bolted on, I picked up a tenth. I would have liked to have put the TTI's on it, but didn't have budget for it. But after reading some other threads about them on comparisons, I may have not needed them.
