Pacemaker 3" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Pipe Only for HSV VU & VY Series 1 Ute (5.7L V8) - PP5363-74

Unlock massive horsepower gains and unleash an ultra-aggressive muscle roar from your 5.7L LS1 engine with the Pacemaker Sport Systems complete exhaust solution. Specifically engineered to clear the distinct utility floor pan and chassis layout of the HSV VU and VY Series 1 Maloo 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 massive 3" 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 HSV VU and VY Series 1 Utility (Ute) models (2000–2003) 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 high-performance Maloo utility 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.
  • 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 3" (76mm) pipe structure ensures a smooth, constant internal diameter to prevent flow restriction.
  • Hanger Integration: Designed as a direct bolt-on layout utilizing the vehicle's factory mounting points.

Important Fitment Notes:

  • Specifically engineered to fit HSV VU and VY Series 1 Utility (Ute / Maloo) platforms powered by the 5.7L LS1 engine (2000–2003).
  • Utility Specific Chassis Layout: This configuration features tailor-formed exhaust pipe lengths and bends designed precisely to mount cleanly under the utility bed structure and will not adapt correctly to Sedans or Wagons.
  • Full kit scope: Includes 1 7/8" Tuned Performance Extractors, 3" High-Flow Metallic Catalytic Converters, and a complete 3" 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 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 under the tray.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.
