Adding "Premium" definitely changes the tone.
Overwhelming power and response with an increase of approximately 30 to 50 horsepower.
"Premium" is the ultimate front pipe for perfect GT-R tuning.

Although it depends on the boost setting, you can expect an increase of 30 to 50 horsepower compared to a regular commercially available sports front pipe. And the response is also much better. The layout, which is much longer than a normal front pipe (ø70W→ø90), is a completely original profile that was created after extensive consideration and testing of the GT-R.
This is an overwhelming unique know-how that could only be developed by Kakimoto Kai, the pioneer of front pipes who first created and produced the concept of front pipe tuning, which is now commonplace.
The sound of a GT-R with the same tuning content, with and without Premium, is clearly different. "Sound is performance" is what Kakimoto Kai has always said, and the dry, exquisite sound is proof of the performance of the Premium.
Not only does it improve the driving feel and response, but it also produces astonishing results in power checks.
There is no better way to tune your GT-R than adding the Premium Front Pipe.
*The genuine catalyst will be removed.
*The "Front Pipe Premium" cannot be installed alone.
*It must be installed together with the dedicated muffler "HYPER 2000 FULLMEGA N1+ Premium compatible."

An ultra-Spartan Egoistec model that is compatible with the Premium Front Pipe to maximize the power of the RB26DETT.
"HYPER2000 FULLMEGA N1+ for Premium"

Kakimoto's soundproofing mechanism originally utilizes highly advanced know-how to set the volume to street level while keeping power loss to a minimum, but this HYPER 2000 FULLMEGA N1+ for Premium model employs an inner megaphone mechanism to further minimise power loss caused by the silencer, making the punched pipe inside the main muffler shorter than usual and extending the tapered megaphone-structured tailpipe to the inside of the muffler.
Furthermore, the unevenness caused by the covers at the joints of the main pipe, punched pipe, and tail pipe has all been flattened to prevent exhaust resistance, in order to thoroughly improve exhaust efficiency.
This is a unique feature of Kakimoto Kai, and this type of treatment is almost nonexistent in other mufflers on the market, but this attention to detail has a not inconsiderable effect on horsepower.
By simultaneously installing the HYPER2000 FULLMEGA N1+Premium compatible and the premium front pipe Premium that is the ultimate in GTR tuning, an incredible power increase has been achieved.
We hope you will enjoy the sound and performance that only Kakimoto Kai can provide.

*The front pipe and spread support in the image on the right are sold separately.
*This muffler is exclusively for the "Front Pipe Premium." (See below for details)

Dual penetration directly after the turbine. The industry's only ultra-Spartan Egoistec model.
"HYPER 2000 FULLMEGA N1+FULL DUAL"

HYPER 2000 FULLMEGA N1+FULL DUAL is specially designed for the Skyline GT-R BNR32, BCNR33, BNR34, and the Fairlady Z twin-turbo Z32.

The same inner megaphone structure and internal structure as the HYPER 2000 FULLMEGA N1+ for Premium model unique to Kakimoto Kai pursues thorough exhaust efficiency. This is an ultra-Spartan model that emphasizes good exhaust at high RPMs.

The small ø127W drum and the bullet-shaped ø100W tail drum create a visually impressive sound.
(The Z32 has a ø152mm muffler and ø115mm tails on both sides.)

Although it is a high quality, high performance model, the price is as low as other companies' ø60W models, with a ø70W.

A must-see for anyone who wants to enjoy a fully tuned GT-R or Z32 on the circuit without being bound by safety standards.

*Since this is a replacement type that is installed immediately after the turbine, the original catalyst will be removed.
