Pacemaker Performance Twin 2.5" Cat-Back Exhaust System for Holden Statesman & Caprice WM Series (Gen IV 6.0L V8) - PP5381-06

Maximize downstream airflow efficiency, accelerate exhaust gas velocity, and unlock a deep, authoritative Australian muscle car growl from your small-block engine with the Pacemaker Sport Systems complete twin 2.5-inch performance cat-back exhaust solution. Custom-engineered specifically to handle high gas volumes and optimize torque tracking on Holden Gen IV 6.0L V8 long-wheelbase luxury powerplants, this premium setup is precisely shaped to map the elongated floor pan lines, spacious luxury underbody cavities, and multi-link independent suspension constraints unique to the WM series architecture. By replacing your stock, restrictive factory plumbing downstream of the catalytic converters with a high-flow mandrel-bent performance construction, it rapidly clears spent exhaust gases to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker pairs this free-flowing intermediate path with patented V-Tex technology and signature double-skinned mufflers, delivering an uncompromised, thumping V8 roar outside under throttle while actively engineering out harsh interior cabin boom or long-wheelbase body resonance to preserve a completely clean, drone-free luxury highway cruising experience.

Note: Fits Holden Statesman and Caprice WM variants built from August 2006 to June 2013 including Series I and Series II models equipped with the Gen IV 6.0L V8 engine configuration; does not fit short-wheelbase Commodore (VE) Sedan, Sportwagon, or Utility variants due to structural length, intermediate pipe extensions, and rear routing path differences.

Features:

Precision-manufactured in Australia to deliver a premium flow upgrade, maximum structural longevity under intense heat, and a refined performance acoustic profile for the premium Holden long-wheelbase platform.

  • True Performance Cat-Back Layout: Comprehensive high-efficiency performance line engineered to bolt up securely downstream of the factory or premium aftermarket catalytic converter sections.
  • Long-Wheelbase Specific Clearance: Custom-tailored plumbing path configured to route cleanly beneath extended luxury chassis floors, rear subframes, and vehicle-specific bumper exit paths.
  • Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue.
  • Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent restriction.
  • V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of sports layouts without restricting gas velocity footprints.
  • Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel rear mufflers offer premium outer case reinforcement, completely preventing internal acoustic packing blowout under heavy thermal load constraints.
  • Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing factory rubber hanger positions—no custom fabrication required.

Important Fitment Notes:

  • Specifically engineered to fit long-wheelbase Holden Statesman and Caprice WM variants built from August 2006 to June 2013 (covering both Series I and Series II models).
  • Long-Wheelbase Routing Geometry: Due to extended vehicle specifications, custom underbody layout cavities, and alternative structural lengths designed precisely to clear premium chassis rails, this layout features distinct intermediate tubing path extensions. It will not adapt to standard wheelbase Sedan (VE), Sportwagon, or Utility (Ute) options.
  • Direct bolt-on architecture interfaces seamlessly with original vehicle-specific rubber hanger brackets downstream of the catalytic converter assemblies. No custom fabrication, cutting layout mapping, or welding is required.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, verify strict exhaust component alignment, and ensure completely gas-tight structural seals.

Fantastic toy for the pups!
My dog is in LOVE with these toys. I've been buying them once a year for the past few years and although I'm sad to see the price go from $11 to $19, it's a staple toy in our house. Great for treats inside of it for enrichment, peanut butter freezes in the prong great and it keeps my girl busy.

Easily destructible
NOT for aggressive dog. My Boston Terrier is a chewer and had this destroyed in a few hours and it is a choking hazard. I threw it away the same day!!! Do not purchase if your pet is a chewer!!!

Works fantastic.
Works great. I have 2 little dog. Both part min pin. But they can chew. They have tartar and I am trying everything to help them, with powder in the food, and a liquid for the water. That's been helping but they will not let us brush their teeth. SO I know they love bones, but I didn't want them to keep eating them, like the ones for fresh breath and cleaning the teeth. They just eat them and get fat. WELL, these bone here that I bought, are fantastic!!. I only stick a few treats inside the seams and middle and they both chew away getting only a little treat at a time bit they have to work for it. So now they chew longer and get very little treats. Yes, my dogs can chew and they have already done some damage on this bones, but for the price and what it does, Its a win win. I will try to get a video or pics later.

Good Product But I Need Something Indestructible
These were advertised for aggressive chews, but my 2 mini schnauzers puppies quickly bit off the little prongs within an hour. I didn't put food inside them; I just wanted them for chew toys. Well, they were not hard enough for them. The size was perfect for puppies, but they were not durable enough for my 'heavy' chewers. I hate I can't find chew toys they can't destroy! Now they bring in sticks and mess the house up.

Works great with toothpaste.
They lasted longer than most toys but eventually my dog was able to tear them up.
