Gather round erryone, for I have some Supra lore for you:
Back in the 90's, if you wanted to supplant your 2JZ-GTE's stock twin turbos with a single snail, you had basically three options: Powerhouse Racing's log-manifold "Street Turbo Kit" made in Texas (they were the first on the market in the US and
possibly the world with a single turbo kit in 1994, and are still around today making extremely high quality Supra parts including this kit), Greddy's indestructible tubular-manifold T-78 turbo kit which hit US shores sometime around '97, and finally the RPS tubular-manifold kit, made in California featuring a variety of Turbonetics turbos to choose from, up to the then-massive T-72(mm inducer) offering.
What made the RPS kit special amongst all other kits of the time (and still to this day) is its manifold, which is/was an equal-length, thin-walled offering (thinner than anything anyone would dare to make today for longevity's sake):
This particular mix ended up providing the 2JZ with an exhaust note somewhere between a sportbike and an F1 car of the era, with the bass turned up. Of note:
Craig Lieberman's Supra that was used in the 1st F&F movie featured a RPS kit with a T-66, and together with a rare & long-discontinued Greddy Power Extreme exhaust, it's still actually one of the best sounding MKIV's that ever was, in my opinion (gets real good at 1:18):

RPS/Greddy PE combo like the F&F1 car again:

The RPS kit was discontinued in the '04-'05 time-frame, and the manifold is highly coveted now (though many have cracked and been re-welded by now due to the thin-walled construction). The company is still around making performance clutches under the same brand name. Rob Smith, the proprietor, has been approached to make more, but he'd only do it for something like $3k per manifold, so that never happened.
The demand was so great in the Supra community for used RPS manifolds that in early 2011, Sound Performance in Chicago stepped up to the plate and released the replica that you hear on that MKIII. It's not as thin-walled, so a bit of the "ring" is gone from the exhaust note, but it's as close as you can get to a new RPS manifold today that won't fall apart, and it has some minor improvements to the wastegate plumbing to avoid boost-creep and the like:
And that concludes our lesson for today. If you need me, I'll be shuffling dust around in
my library.
