Motordyne LTXYZ Long Tube Headers

Modular Engineering for Maximum Versatility

Modular System Architecture
The Motordyne LTXYZ Long Tube Headers feature a precision-engineered modular design, providing users with the flexibility to adapt their exhaust configuration as needed. The system offers the following interchangeable modules:

• Straight Pipe
• Side-Branch Helmholtz Resonator
• Catalytic Converter

These modules allow for rapid reconfiguration without requiring extensive downtime. Traditional headers on the VQ37VHR engine often necessitate complex installations, taking professional shops one to two days for completion. With road-course races and time attack events often mandating catalytic converters, the LTXYZ’s modular approach ensures compliance without the need to pre-plan extensive disassembly.

Why the Motordyne LTXYZ Headers Stand Out

The LTXYZ headers enable in-situ configuration changes in under 30 minutes—right from your driveway. Simply elevate the vehicle on jack stands to access the undercarriage, where the modules are easily removable. Each module is secured with two bolts and a single clamp per side, ensuring rapid installation and seamless adjustments.

This modularity allows for customized performance and sound tailored to specific driving conditions. Whether optimizing for daily driving, competitive racing, or emissions compliance, the LTXYZ system provides unmatched adaptability.

Precision Construction and Material Integrity

Every component of the LTXYZ headers is crafted from 304L stainless steel alloy, ensuring durability and resistance to corrosion. The tubing is polished to enhance its anti-corrosion properties. All connections and flanges are TIG-welded with argon back-purging, ensuring clean, oxidation-free welds on both internal and external surfaces.

Engineered for Performance

The stepped header design enhances horsepower and torque output, with a bias towards top-end power. The primaries feature a transition from 1-5/8″ to 1.75″ tubing, optimizing exhaust gas flow. This expansion leads to a 2.5″ merge collector equipped with an internal spike diffuser, maximizing exhaust velocity and scavenging for superior performance gains.

Conclusion

The Motordyne LTXYZ Long Tube Headers embody the best in modular engineering, providing unparalleled versatility, ease of use, and performance. Whether for track events or street use, this system offers precision-crafted functionality that delivers measurable improvements in both power and adaptability.
