Pacemaker 2.5" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Pipe Only for Holden VY Series 2 & VZ Wagon (5.7L V8) - PP5363-33

Unlock major horsepower gains and unleash an ultra-aggressive muscle roar from your 5.7L LS1 engine with the Pacemaker Sport Systems complete performance exhaust solution. Specifically engineered to clear the distinct floor pan and rear bumper geometry of the Holden VY Series 2 and VZ Station Wagon platforms, this high-flow setup is configured with a high-volume "Rear Pipe Only" exit plan instead of a standard rear muffler assembly. Featuring large-diameter 1 7/8" primary tuned headers paired with a smooth 2.5" mandrel-bent layout, it delivers maximum exhaust gas velocity while providing an unrestricted bark. It is the ultimate match for cammed, modified, or high-scavenging 5.7L builds that demand peak top-end performance and a standout racetrack sound. Note: Fits Holden VY Series 2 and VZ Wagon models (2003–2006) equipped with the 5.7L LS1 V8 engine.

Features:

Precision-manufactured in Australia to deliver the absolute peak in flow efficiency, heavy-duty scavenging, and raw acoustic output for the long-roof Commodore platform.

  • Complete Headers Setup: Total kit featuring 1 7/8" primary tuned headers, 3" hi-flow cats, and active piping sections.
  • Rear Pipe Configuration: Built with a straight-through rear pipe replacing the standard tail muffler for maximum exhaust bark and unrestricted flow potential.
  • 1 7/8" Tuned Headers: Upgraded large-tube design engineered to optimize top-end power potential and high-RPM volumetric efficiency.
  • Premium Materials: Constructed completely from durable Exhaust Grade 409 Stainless Steel for superior longevity under high thermal stress.
  • Mandrel Bent Tubing: Heavy-duty 2.5" (63.5mm) pipe structure ensures a smooth, constant internal diameter to prevent backpressure.
  • Hanger Integration: Designed as a direct bolt-on layout utilizing the wagon's factory mounting points.

Important Fitment Notes:

  • Specifically engineered to fit Holden VY Series 2 and VZ Station Wagon platforms powered by the 5.7L LS1 engine (2003–2006).
  • Wagon Specific Floorpan: This configuration features tailor-formed exhaust pipe lengths and bends designed precisely to mount cleanly under the wagon layout and will not adapt correctly to Sedans or Utes.
  • Full kit scope: Includes 1 7/8" Tuned Performance Extractors, 3" High-Flow Metallic Catalytic Converters, and a complete 2.5" exhaust system featuring a straight-through rear section with a rear pipe only.
  • The "Rear Pipe Only" deletion of the rear resonator creates a significantly louder, unfiltered acoustic profile compared to traditional full-muffler configurations.
  • Direct bolt-on design reuses vehicle-specific factory hanger positions.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance and tight seals.

Dog Loves It, But Durability/Safety Major Issue
Size: 8 Inch, Color: Tree Branch
My 9 month old Frenchie loves it, but she got pretty sick this weekend and was vomiting all day...next day she finally threw up a big chunk of this toy...just beware if your dog is a heavy chewer, this may not be the right fit for you. Not the best durability...

She loves them, therefore I love them too

My furbaby LOVES these, especially the peanut butter flavored ones. I still regularly brush her teefers, but these do help with dental care.

Made mostly of POLYPROPYLENE PLASTIC and should not be injested.
Size: 8 Inch - 2 Pack, Color: Tree Branch
BAD PRODUCT. DO NOT BUY THESE FOR YOUR DOG. They are made mostly of POLYPROPYLENE PLASTIC. It even says on the package - "CAUTION: Product is not intended to be eaten or ingested. If you believe your pet has swallowed a piece, please take away and contact veterinarian if needed. Our dachshund went to town on one of these and had diarrhea for two days and cost us several hundred dollars in vet bills to do x-rays and medicine for the poor dog. What do you think a dog is going to do with a dog chew? Just find another product. This one isn't worth it.

It'll only last a week
Size: 5 Inch, Color: Classic Bone, Size: 5 Inch, Color: Classic Bone
We've only had it a few days and she's already half way through it. It won't last the week. She doesn't eat it, she spits out the pieces. If you buy it was a consumable, totally worth the money. I'll probably buy my power chewer a couple a month
