Pacemaker Tri-Y Performance Headers for Holden VT Series 1 5.0L V8 1997–1999 - PP5050-03

Pacemaker Performance Tri-Y Headers for Holden VT Series 1 (5.0L V8) - PP5050-03

Unlock major low-to-mid range torque gains and give your iron-block small block a deep muscle rumble with the Pacemaker Sport Systems premium Tri-Y performance headers. Specifically engineered to extract maximum efficiency from the classic Holden 5.0L (304ci) V8 engine, this high-flow collector setup is precision-molded to fit perfectly within the engine bay clearance paths, steering rack lines, and independent front chassis layouts of early VT Commodore configurations. By splitting the exhaust pulses into paired secondary pipes (Tri-Y layout), these headers optimize exhaust gas velocity and scavenging performance to completely remove power-robbing backpressure right out of the cylinder head. As Australia’s premium exhaust innovator, Pacemaker manufactures these headers from heavy-duty steel to deliver exceptional durability and temperature control under high thermal stress, providing an aggressive performance bark on throttle and making it a massive upgrade over restrictive factory cast manifolds. Note: Fits Holden VT Series 1 models (1997–1999) equipped with the 5.0L Holden V8 engine configuration; does not fit Series 2 Gen III LS1 builds.

Features:

Precision-manufactured in Australia to deliver premium cylinder scavenging, high-stress durability under intense heat, and a classic muscle car exhaust note.

• Tri-Y Design Architecture: Advanced multi-secondary pipe layout engineered explicitly to boost low-to-mid range torque retention and accelerate overall exhaust gas clearance.
• Heavy-Duty Base Flanges: Precision-machined, thick mounting plates ensure a perfect face seal against the cylinder head to completely prevent exhaust gas leaks.
• Mandrel Bent Tubing: Rigid plumbing structure guarantees a smooth, uniform internal pipe diameter through all primary bends to optimize gas velocity.
• Engine Bay Clearance: Custom engineered to clear the steering rack, starter motor, and crossmember paths of the VT engine bay configuration without modification.
• Australian Made Quality: Proudly designed and manufactured in Australia to withstand high thermal loads and extreme driving demands.

Important Fitment Notes:

• Specifically engineered to fit Holden VT Series 1 platforms powered by the original Australian 5.0L V8 iron-block engine configuration (1997–1999).
• Series Specific Engine Fitment: This product only fits the early Series 1 production run featuring the traditional Holden V8. It will not fit VT Series 2 or subsequent platforms equipped with the 5.7L Chevrolet Gen III LS1 aluminum V8 block.
• Product scope: Set includes performance Tri-Y driver and passenger side extractors only (intermediate piping and catalytic converters are sold separately).
• Designed to drop directly into standard engine bay alignments, re-using factory engine bay clearance tolerances.
• Professional automotive performance technician installation is highly recommended to guarantee ideal steering clearance and a strict, leak-free cylinder head seal.
