P2R J-Swap Big Tube Race Header

P2R J-Swap Big Tube Race Header - 304 Stainless Steel

The P2R J-Swap Big Tube Race Header is engineered to unlock the full performance potential of your J-Series engine swap. Designed specifically for high-output racing applications, this header utilizes stepped piping diameters to optimize exhaust flow and increase horsepower across the powerband.

Constructed from high-quality 304 stainless steel, this race header provides the durability required for demanding track use while maintaining a show-quality polished appearance. Whether you are building a dedicated drag car or a high-performance street machine, the P2R Big Tube Header delivers the flow characteristics necessary for a competitive J-Swap.

Key Features

• **High-Flow Design:** Features 1.75" primaries merged into a 2.5" center section and a 3.0" outlet for maximum exhaust scavenging.
• **Premium Construction:** Manufactured from full 304 stainless steel with a polished finish for superior durability and corrosion resistance.
• **Race-Ready Components:** Includes a 3" flex pipe and an integrated O2 bung to facilitate custom exhaust fabrication.
• **Optimized Clearance:** Specifically engineered to clear the sub-frame on supported J-Swap chassis.

Specifications

• Primary Diameter: 1.75"
• Center Section: 2.5"
• Outlet Diameter: 3.0"
• Material: 304 Stainless Steel
• Finish: Polished
• Connection: V-Band (Flex pipe included)

Fitment / Applications

• 1999-2003 Acura TL (J-Series Swap)

• 1998-2002 Honda Accord V6 (J-Series Swap)
• Honda Civic EG/EK (J-Series Swap)

Notes

• This is a race swap header and is not a direct bolt-on to factory exhaust systems. Custom fabrication is required to connect the V-band to your exhaust.
• On 99-03 TL, 01-03 CL, and 98-02 Accord V6, the header sits close to the sub-frame. New engine mounts or sub-frame notching is recommended to prevent contact.
• For EG and EK Civic swaps using Hasport brackets, slight notching of the rear bracket is required for proper clearance.

Pro Tip: To ensure maximum clearance and prevent sub-frame contact, we highly recommend installing new performance engine mounts alongside this header.
