[New Release] Renewed HPI turbo outlet pipe for BNR32 / BCNR33

Price: 95,000 JPY (Excl. Tax)

Compared to the conventional model, the exterior features an integrated die-cast construction combining the

turbine-side flange and the main body. The finish of the sensor mounting section has been updated, and the

entire assembly—including the outlet-side flange—is now crafted from stainless steel.

Furthermore, the internal structure of the main body has been redesigned with a slightly expanded clearance

from the inlet to optimize exhaust efficiency!

[New Release] Renewed HPI turbo outlet pipe for for S14 / S15

Price: 36,800 JPY (Excl. Tax)

Compared to the conventional model, the exterior has been upgraded to an integrated die-cast design that

combines the turbine-side flange and the main body. The finish of the sensor mounting section has been

completely refreshed, and the entire unit—including the triangular outlet-side flange—is constructed entirely

from stainless steel.

The interior of the main body also features a slightly expanded clearance at the exhaust inlet to optimize flow

and enhance exhaust efficiency.

Price: 105,000 JPY (Excl. Tax)


Polished stainless steel custom intake manifolds for high-performance automotive engine, engine components for car tuning.
HPI Renewed Stainless Steel Turbo Outlet Pipe for Nissan Skyline GT-R BNR34 (RB26DETT). Engineered to lower secondary backpressure and maximize turbine exhaust efficiency, this high-durability stainless steel outlet pipe features a Φ76 front-pipe connection. Its uniquely contoured, widened shape smoothly guides exhaust gases to unlock the true power and response of the twin-turbo RB26 engine.

This renewal pushes turbine exhaust efficiency to its absolute limit, extracting the vehicle's best potential!

For a turbo outlet pipe, achieving high durability while reducing secondary backpressure to improve exhaust

efficiency is absolutely critical. The renewed HPI Turbo Outlet Pipe features a slightly widened version of its

uniquely contoured, expanded shape, allowing it to guide exhaust gases from the turbine to the front pipe

even more efficiently. By maximizing exhaust flow and improving response, it unlocks the true potential

inherent to the turbocharger.
