While the Mustang hobby can easily be broken down into several categories, being in the center of the sometimes-fierce competition between aftermarket parts manufacturers is one of the most exciting parts of our job. And, as you can imagine, we're always hearing from companies that constantly try to one-up their competitors, by having us review their newest offerings for late-model 'Stangs.

With our economy in a better shape than it was a few years ago, manufacturers once again are starting to produce seriously cool hardware for Ponies of all ages, especially the '11-'12 5.0 Mustang GT. We acknowledge our coverage of this hot, new 'Stang has been intense. However, we assure you we certainly haven't lost sight of the cars before it. Not in the least. So, with that idea in mind, this exclusive highlights a wicked, new concept from One Piece Products of Whittier, California, that actually isn't applicable to the SN-10 Mustangs; nor can it be installed on Fox-body, SN-95, or New Edge Mustangs.

Ben Tapia, owner and chief designer at One Piece Products, developed a set of replacement quarter-windows for '05-'09 coupes that adds serious cool to S197s. And what in the world could possibly be cool about '05-'09 quarter-glass, you ask? Well, Ben has come up with a way to make those fixed rear windows actually open.

If you think back through the late- model Mustang's history, hardtop ('79-present hatchbacks and coupes) Ponies have never been equipped with quarter-glass that can be opened, or fully removed. Ben's breakthrough concept, the One Piece Series VI Power Quarter Pop-Out Kit (PN OPP0509; $795), is a bolt-on, power-window system that, when open, dramatically changes an S197 coupe's rear-quarter styling and more importantly, makes it possible for fresh air channel to through the rear-seat area.

Once the kit is installed, simply pressing one or both dash-mounted switches opens the small quarter-windows as wide as 2 inches; just enough to give a Pony's rear flanks a killer new look and let outside air enter and completely circulate throughout the Mustang's cabin area.

A setup like this is exactly the type of new product we like to see--something that's truly different. Better yet, it bolts on without too much ado. Installation can be handled by One Piece Products if you're in SoCal, or ambitious do-it-yourselfers can get it done in their home garage.

If you follow us on Facebook, we trust you've already seen a video clip of this exciting, new window system in action, on Gabe Garcia's clean S197. Now you can check out the following photos to see how the window magic happens. Ben's window setup definitely is the hot ticket for '05-'09 hardtop 'Stangs.

Horse Sense: The '74-'78 Mustang II is considered by many automotive writers as the Mustang that should never have been built. While the little Ponies are bashed, even by Ford loyalists, for many varied reasons, we do have to thank Mustang II for their rack-and-pinion steering and front-disc brakes, which have been standard equipment in every 'Stang since that time. The question is, though, why are we even mentioning Mustang IIs now? Well, they're actually relevant for this report, as Ford's Intermediate 'Stangs were the last hatchback and coupe Mustangs to feature rear quarter-windows that opened (hatchbacks/pop-outs, coupes/crank-operated). Something to think about when you hit the trigger on the system being featured in this report!
