I'll preface by stating - beauty is in the eye of the beholder. This alone should be the only reason why anyone elects to modify their ride. Doing so to invoke positive responses from peers, to justify your own existence plays into poor self-worth and tribalism which unfortunately - is rampant.
We, as in those who elect to modify our rides, are a very small minority of the driving population on this continent. It's getting significantly smaller every year now.
As NOMAD and others aptly point out; even the number of Hemi-equipped platforms seriously pales in comparison to Chevy and Ford. It took many years - after(!) the LX platform was released - for legitimate performance parts to arrive on the scene. We were, and still are, a very small segment of the Aftermarket Performance Industry. We simply do not have the volumes of dedicated owners who wish to mod their rides. We, even with Hemi-equipped rides, will never dominate the Aftermarket Industry. In fact the writing has been on the wall for some time; our days are numbered as it is - even for over-powered OEM vehicles.
So - finding legitimate performance parts for any of the V6 offerings; let's just say there simply is not a market - as seen by the Aftermarket Industry.
Whatever the other reasons, mostly emotionally-driven, why the V6 engine and / or equipped platforms is low on the totem pole will never change. To me, souping up any sort of 4-door sedan is simply cowing to what the industry has elected to offer us. To me, a station wagon is a has-been from an era of suburbanism and the bullsh!t patriarchally-driven misnotion that this is what housewives were allocated to drive. So changing one into a machine that can seriously, when required, embarrass that patriarchal mindset (five / six-figure sportscars on a road course for example) stands on it's own merit.
I built the (my) wagon for me...cause that's ALL that matters. It meant designing and building a lot(!) of parts to achieve the end-result. That(!) was the enjoyable part - plus the results while driving (sidenote: I view car shows as an opportunity to enjoy the work of others and learn - not any sort of affirmation. Leaving the Magnum out on the street allows me to walk around admiring other people's work till I get bored, get back in the car and enjoy the rest of the nice day day - actually driving :^).
With your own machine, that is all that should matter to you. Build stuff, or solicit those who can offer guidance to allow you build stuff. Don't let the egos of others dictate what you like and / or find enjoyable or what you can or can't do...
