Unlock significant horsepower gains and unleash a deep, uncompromised muscle roar from your 5.7L LS1 or 6.0L Gen IV engine with the Pacemaker Sport Systems heavy-duty twin 2.5" performance cat-back exhaust solution. Specifically engineered for the classic rear floor pan geometry of standard-wheelbase Holden Commodore and HSV sedan configurations across the entire VT, VX, VY, and VZ generations, this high-velocity system bolts up directly to existing catalytic converter locations. As Australia’s premium exhaust innovator, Pacemaker integrates elite acoustic engineering with patented V-Tex technology and signature double-skinned mufflers to offer an aggressive, commanding exterior rumble while completely counteracting intrusive cabin boom or highway drone. Note: Fits Holden and HSV Sedan models (1999–2006) equipped with 5.7L or 6.0L V8 engines.

Features:

Precision-manufactured in Australia to deliver a premium flow efficiency upgrade, heavy-duty scavenging, and an unmatched depth of sound for the V8 sedan platform.

• True Cat-Back Setup: Complete twin performance mid-section and tail exit assembly designed to secure cleanly behind your factory or aftermarket converters.
• Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel for superior longevity under high thermal stress.
• Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structures guarantee a completely uniform internal diameter to prevent restrictive backpressure.
• V-Tex Technology: Advanced internal anti-drone configuration filters out harsh cabin boom frequencies while retaining deep exterior exhaust notes.
• Signature Mufflers: Double-skinned 409 Stainless Steel mufflers offer superior casing strength, zero internal packing blowout, and refined tonal control.
• Direct Bolt-On Layout: A 100% full bolt-up design matching original mounting points under the sedan chassis—no custom fabrication or modification required.

Important Fitment Notes:

• Specifically engineered to fit standard-wheelbase Holden Commodore and HSV Sedan models (VT, VX, VY, and VZ Series) from 1999 to 2006.
• Sedan Specific Layout: This configuration features tailor-formed routing lengths and bracket placements matching the standard sedan floor pan. It will not adapt correctly to long-wheelbase models (Statesman/Caprice), Utes, or Station Wagons.
• Full kit scope: Comprehensive cat-back line including high-velocity center sections and signature double-skinned rear mufflers for optimal performance and resonance control.
• Direct bolt-on design reuses your vehicle's factory rubber hanger positions and standard converter paths.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance and tight seals under the floor.
