Powerhouse Amuse: Titanium Art and the S2000 GT1
Powerhouse Amuse's S2000 GT1 is the definitive tuned S2000 — a Tsukuba time attack legend. Their R1 titanium exhausts are the most copied exhaust design in JDM history.
Powerhouse Amuse: Titanium Art and the S2000 GT1
Powerhouse Amuse (often shortened to "Amuse") is a Kanagawa-based tuning house that built one of the most iconic JDM demo cars of the 2000s: the S2000 GT1. Amuse is also responsible for the R1 titanium exhaust, arguably the most copied exhaust design in JDM history.
The S2000 GT1
The S2000 GT1 was developed in the early 2000s as Amuse's flagship demo car. It featured:
- F20C turbocharged, later F22C — making 400+ hp
- Full wide-body aero package by Amuse's in-house designers
- Massive rear wing, front splitter, and canards
- Light weight chassis preparation
- Recaro seats, roll cage, stripped interior
- Tsukuba time of under 1:00 — one of the fastest S2000s in history
The GT1 appeared on countless magazine covers, Option Magazine cover stories, and Best Motoring episodes. It became the defining "built S2000" image worldwide.
The R1 Titanium Exhaust
Amuse's R1 titanium exhaust is their most famous product. The system uses:
- Full titanium construction (saves 10+ kg over OEM)
- Slash-cut tips with characteristic Amuse diamond pattern
- Unique muffler design with minimal packing for a raw titanium sound
- Hand-welded construction at Amuse's Kanagawa facility
R1 exhausts are made for S2000, NSX, RX-7 FD3S, and a few other platforms. They are copied by every major exhaust maker worldwide, but the original Amuse units have a characteristic tone and build quality that cannot be replicated.
The Catalog
Beyond the R1 exhaust, Amuse's parts catalog includes:
- Aero packages (S2000 GT1, NSX, RX-7 widebody kits)
- Wheels (Amuse Shallow Concave are iconic)
- Coilovers (in collaboration with Ohlins and others)
- Intakes and cooling
- Complete turn-key builds
The Philosophy
Amuse's approach is refined power with dramatic visuals. Where Mine's would hide the tuning behind a stock appearance, Amuse embraces the widebody, the big wing, the titanium exhaust visible from the side of the car. But the engineering underneath is deeply serious — Amuse cars survive track day abuse without temperament.
The Workshop
Amuse is headquartered in Kanagawa and operates a full machine shop, fabrication facility, and dyno. The shop is open to customers by appointment only. Amuse builds remain some of the most desired JDM demo cars when they surface at auction.
Why Amuse Matters
Amuse proved that refinement and drama could coexist. Every Amuse build looks exotic but performs as a serious track weapon. The S2000 GT1 single-handedly elevated the S2000 from "sporty convertible" to "serious Time Attack platform" in the global consciousness. The R1 exhaust defined what a tuned JDM car should sound like for an entire generation.
