Free the VR30 exhaust path without deleting the catalysts
HKS 33006-KN001 replaces the restrictive factory front pipes with a matched stainless pair engineered for the twin-turbo VR30DDTT. The larger tubing and low-cell-count catalysts reduce backpressure while retaining a catted layout for street-focused builds.
Key Features
- HKS 33006-KN001 uses dual 60 mm tubing in place of the factory 45 mm sections.
- A 100-cell catalyst is installed on each side.
- HKS reports approximately 50 percent lower backpressure than stock.
- SUS304 stainless construction supports corrosion resistance and repeat heat cycling.

About HKS
HKS develops matched intake, exhaust, suspension, and engine systems through vehicle-specific testing. HKS 33006-KN001 applies that approach to the VR30DDTT exhaust path rather than using a universal pipe layout.

FAQ
What is the 33006-KN001?It is the catted front pipes configuration described on this page for the verified application and included components.
Will this fit every version of the listed vehicle?No. Match the year, model, chassis, engine, drivetrain, transmission, and exclusions in the Fitment table before ordering.
Is professional installation recommended?Yes. Correct installation, torque procedures, system checks, and any required alignment or bleeding should be completed by a qualified technician.
Does the kit include everything shown in the fitment notes?The package contents are limited to the items listed under What's Included. Related or supporting parts are separate unless explicitly listed there.
Can this be used on a modified vehicle?Possibly, but existing modifications can change clearance, compatibility, calibration, or installation requirements. Inspect the full combination before installation.
What should be checked after installation?Check fastener torque, leaks or clearances where applicable, warning lights, fluid level or alignment as relevant, and inspect again after the initial break-in period.
Is the product universal?No. It is vehicle-specific and must be matched to the verified application above.
Where can I find the exact application limits?Use the Fitment and Specifications tables on this page. Those sections contain the verified model, configuration, and exclusion details.
Installation Instructions
- Allow the exhaust to cool and raise the vehicle securely.
- Disconnect the oxygen sensors and free their wiring clips before removing the factory pipes.
- Install the supplied gaskets and both HKS pipes without forcing the flanges into alignment.
- Reconnect the sensors, torque all hardware to the HKS instructions, and check for leaks.
Important: Emissions compliance must be confirmed for the installation jurisdiction.
