PLM  B-Series Tri-Y Big Tube Header B18 B20

Upgrade Your Honda B-Series Performance with the Private Label Mfg. Tri-Y Big Tube Header

The Private Label Mfg. Tri-Y Big Tube Header offers a performance upgrade specifically designed for Honda B-Series engines (B18, B17). This header utilizes a unique Tri-Y design and larger diameter tubing to optimize exhaust flow characteristics, resulting in measurable power gains.

Technical Benefits:

• Tri-Y Design: This three-into-one configuration promotes balanced pulse extraction from each cylinder, minimizing exhaust backpressure and scavenging unburned fuel for improved combustion efficiency.
• Larger Diameter Tubing: Compared to the stock header, the increased tube diameter reduces flow restrictions, allowing for efficient exhaust gas evacuation and reduced pumping losses. This translates to improved engine breathing and higher peak power output.
• Mandrel-Bent Stainless Steel Construction: The smooth bends and high-quality stainless steel construction guarantee optimal flow characteristics and superior durability against corrosion and heat, even under demanding driving conditions.

Performance Improvements:

• Increased Horsepower & Torque: Expect measurable gains in both horsepower and torque across the RPM range, particularly in the mid-range where the Tri-Y design excels.
• Improved Throttle Response: The reduced backpressure translates to quicker engine response to pedal inputs, enhancing overall driving feel and control.
• Enhanced Exhaust Note: The optimized flow path and larger diameter tubing produce a deeper, more pronounced exhaust note, adding a sporty touch to your driving experience.

Installation Considerations:

• Works with A/C when you use slim fans and re-route A/C lines.
• This header is not compatible with A/C in stock factory location setup.  That said, we have seen setups with slim fans and re-route A/C lines and the header can work with A/C with the slim fans and a/c line modification.
• We recommend this header for B18 or B20 engines.

Overview:

The Private Label Mfg. Tri-Y Big Tube Header offers a technically sound and performance-oriented upgrade for your Honda B-Series engine. By optimizing exhaust flow characteristics, this header delivers measurable power gains, improved responsiveness, and a more engaging driving experience. However, due to potential emissions and legality concerns, thorough research and professional installation are highly recommended before purchase and installation.

Fitment: B18 / B20
