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.

Solid basic good denim jacket
Fit Type: Regular, Size: X-Large, Color: Authentic Medium Wash
In direct comparison to Levi’s women’s trucker denim jacket, this one is: slightly heavier denim, less stretchy, less fitted. I kept this one and returned the Levi’s because I wanted the roomier fit. I wish it was a little longer in the body: I’m tall, and it isn’t too short but I’d like a little more length. It feels slightly longer than the Levi’s. I wish the sleeves were longer too. They are probably just right for an average height or shorter person. The armholes could be smaller. The medium wash is a nice medium blue, fairly even in tone. It doesn’t have a lot of stretch but it’s comfortable. The denim is substantial but not too stiff. Overall, it’s a standard good quality denim jacket without any peculiar style elements or weird cut. It’s good!

Fabric way to heavy.
Fit Type: Regular, Size: Medium, Color: White
Cute, but material is WAY to heavy, like the heaviest duty denim I've ever seen. Wanted this to be a cute coverup. If you're needing something while breaking broncos or riding your motorcycle would probably be great. I kept it for a while because it was good quality and well made, but it ended up in the donation pile as I'd never wear this.

Old school denim — not stretchy
Fit Type: Regular, Size: X-Small, Color: Authentic Medium Wash
Fabric used is old school denim — not the thin, stretchy stuff that pretty much everything called “denim” is today. It is 99% cotton (20% of which is recycled cotton) and 1% elastane, but I can’t feel any stretch in the fabric. It is a substantial, non-stretchy denim that gives the jacket really good structure. It has a higher end fit and look than the price would suggest. I wanted a more fitted denim jacket so ordered an XS even though according to the size chart I need a small. (I have a 34.5” bust, 28” waist at 118 pounds 5’4”.) It still buttons over a t shirt or lightweight sweater with freedom for movement/without being tight, but if I wanted a roomy fit or the ability to wear a heavier sweater or sweatshirt underneath and still be able to comfortably button it I would have needed a small. The shoulders are cut broad — I have very broad shoulders and the XS surprisingly fits my shoulders well. This jacket may not be the greatest fit for you if you have very narrow shoulders, unless you are going for an oversized look.

I couldn't get this in my size (medium) so I ordered large. it's a little large in the shoulders, but it still looks good. it is a well made, substantial jacket. I love it!
