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.

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.
  • The "Rear Pipe Only" deletion of the rear muffler assembly creates a significantly louder, racetrack-inspired sound profile compared to full-muffler or traditional resonated setups.
  • 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.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.
