I'm a mazda6 owner doing searches on the MSDS headers. We've also noted an extremely similar aspect between the 2.5 Contour MSDS and the 3.0 Mazda 6s headers.
We started searching the contour forums to see if there were similarities between the two headers because....
1) The headers for the Mazda 6s were rushed out the door, and showed up before intakes, exhausts, or even rudimentary mods were available for the car.
2) The placement of the flex pipe is way off from the stock location. So much so that it causes excessive vibration in the cabin, as well as causing one of the clamps to come loose and require tightening.
3) Some of the piping curves is extremely odd on the 6. It just doesn't make sense. (They could have run a tighter pipe here, or less curves here etc). The fitment is so off that it requires that you hack your alternator heat shield to pieces just to get the piping to fit.
Has anyone noted any additional similarities between the two systems, or talked to MSDS directly about the similarities? Were grasping for straws here as we think the reason these problems exist is because the headers weren't designed for the 6, they were merely "modified" from the contour to fit the 6.
Any information or ideas would be extremely helpful.
Thank you for your time.
