HKS Part Number: 31029-AM004

SUPER TURBO PERFORMANCE DESIGN
The HKS Super Turbo Muffler was engineered around a large 75 mm exhaust path and straight-flow design, giving the system substantially greater flow capacity than the factory exhaust.
HKS specifically designed the system to accommodate hard-tuned 4B11T engines producing up to approximately 500 PS, while simultaneously reducing unwanted exhaust resonance and interior noise during normal street driving.
This makes the Super Turbo an excellent choice for an Evo X that needs a serious performance exhaust without turning the vehicle into an excessively loud, uncomfortable street car.Comfortable Driving with Less Noise
The lower exhaust resonance and interior noise under street driving were reduced.
Use with HKS Metal Catalyzer allows higher performance.

One of the defining features of the Super Turbo system is its enormous 124 mm dual burned exhaust tips.
The blue heat-treated appearance gives the rear of the Evo X the unmistakable period Japanese-performance look associated with high-end HKS systems. The internal slotted design was engineered around HKS\'s effort to control exhaust exit sound while maintaining the aggressive appearance of the system.
JASMA / 4B11T IDENTIFICATION STAMPING
A particularly desirable detail for the JDM enthusiast is the factory stamping visible on the exhaust identifying the 4B11T application.
The system also carries the JASMA marking visible in the photographs, adding important period-correct Japanese aftermarket provenance to an already rare HKS performance component.
Close-up photographs of the stamping are included in the listing. Buyers interested in authentic Japanese-market performance equipment should pay particular attention to this detail.
CONDITION — B GRADE
B GRADE — EXCELLENT OVERALL CONDITION FOR ITS AGE
This HKS Super Turbo Final Edition exhaust is in excellent overall condition considering its age and discontinued status.
There is no rust and no known functional issue with the exhaust. The system does have minor cosmetic imperfections consistent with previous installation, use and storage.
Please review all photographs carefully. The exhaust is being sold as a very good used example, not as a brand-new showroom piece. A nice polish to the canister / exhaust tips and it will bring it up to an A Grade.
A PREMIUM PERIOD-CORRECT EVO X EXHAUST
The Evo X aftermarket has changed substantially over the years. Many of the high-end Japanese exhaust systems that were readily available during the platform\'s peak have since become difficult to source, discontinued or extremely expensive to import.
The HKS Super Turbo Final Edition 31029-AM004 is particularly attractive to enthusiasts who want an authentic HKS system rather than a modern reproduction or generic aftermarket exhaust.
With its 75 mm piping, massive dual 124 mm burned tips, HKS Super Turbo muffler design, 4B11T-specific application and JDM-era construction, this is an excellent addition to a serious Evo X build.
ORIGINAL HKS RETAIL VALUE
HKS lists the 31029-AM004 with an MSRP of $1,800. This is a premium exhaust system rather than an entry-level cat-back.

- Mitsubishi Lancer Evolution X owners

- Final Edition builds
- 4B11T performance builds
