Description
Pacemaker 2.5" Performance Cat-Back Exhaust System with Rear Pipe Only for Holden & HSV V8 Sedans (VT, VX, VY & VZ) - PP5361-02
Unleash an ultra-aggressive muscle roar and increase exit flow velocity 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 maximum-flow system bolts up directly to existing catalytic converter locations. By replacing the traditional tail resonators with an unrestricted, straight-through "Rear Pipe Only" exit assembly, this setup delivers a raw, crisp racetrack bark. It is the ultimate match for cammed, modified, or high-scavenging V8 builds that demand peak track-day performance and a loud, standout exhaust note on the street. 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 refined baseline flow upgrade, maximum durability under intense heat stress, and raw acoustic output.
- True Cat-Back Section: Complete twin performance mid-section and tail exit grouping designed to secure cleanly behind your primary factory or aftermarket converters.
- Rear Pipe Assembly: Deletes traditional rear mufflers/resonators in favor of straight-through performance exit tubes for an unfiltered exhaust rumble.
- Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel to withstand heavy thermal degradation.
- Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structures guarantee a completely uniform internal diameter to prevent restrictive exhaust pooling.
- Performance Center Core: Incorporates dual high-velocity center mufflers to maintain structural exhaust scavenging while dampening fundamental harsh metallic vibrations.
- Direct Bolt-On Layout: A 100% full bolt-up design matching original mounting points under the sedan chassis—no custom fabrication required.
