6.5 Turbo Diesel Headers – High‑Performance, OEM‑Ready Exhaust Solutions
Power‑hungry manufacturers and fleet operators can now eliminate back‑pressure bottlenecks with our precision‑cast 6.5 turbo diesel headers—designed for rapid ROI and zero‑downtime.
Why Purchasing Managers Struggle with Diesel Header Procurement
1. Excessive Back‑Pressure Reduces Power – Studies show up to 12 % loss in torque when standard cast iron headers are used on 6.5 L turbo units.
2. High Unit Costs & Long Lead Times – Conventional suppliers quote $1,200‑$1,500 per set with 8‑12 weeks delivery, inflating CAPEX.
3. Quality Inconsistencies – Cracks and dimensional drift are common in low‑grade alloys, leading to costly warranty claims.
4. Regulatory Barriers – Non‑compliant materials can fail EPA/ISO emissions tests, risking penalties.
5. Limited OEM/ODM Flexibility – Many vendors cannot adapt designs to specific engine bays or mounting constraints.

Frequently Asked Questions (FAQ)
What is the typical lead time for a standard 6.5 turbo diesel header?
Standard GCI‑350 headers ship within 5‑7 business days after order confirmation. Custom OEM designs require 12‑14 days.
Can you provide an aluminum version for weight‑critical applications?
Yes. Our Al‑6061 option reduces weight by up to 20 % while maintaining a maximum service temperature of 950 °C.
What payment terms do you accept for bulk orders?
We support L/C, T/T (30 % deposit, 70 % before shipment), and PayPal for smaller batches.
Do you offer on‑site technical support during installation?
Our engineering team can provide remote CAD verification and, for projects over 100 units, a qualified technician can visit the plant.
How do you ensure compliance with EPA emissions standards?
All headers are designed to meet or exceed Tier 4 emission limits; we provide test reports upon request.
