Pacemaker 2.5" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Pipe Only for Holden VY Series 2 & VZ Ute (5.7L V8) - PP5363-21

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 utility floor pan and chassis layout of the Holden VY Series 2 and VZ Ute 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 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 Utility (Ute) 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 high-performance Commodore 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 2.5" (63.5mm) 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.

Ali and the guys

The story of a lost art student that needs direction. Decides to nanny for a winery owner and his best friends/employees. Fires and lockdowns happen and relationships start. Lots of spice sometimes a little too much I found myself skimming over the parts. Happy ending

Artist Inspiration
Format: Kindle
Ali Fairfax is a twenty-seven year old painter. She is going to an interview for a job as a nanny. She wants to go to art college but has no portfolio pieces to submit. For the last year, her mind goes blank the second she picks up a brush. The nanny interview is at Ashford Winery. Luke Ashford has a son named Charlie who is almost five. Beckett Montgomery is one of Luke’s best friends and he helps Luke run the winery. Hunter Jones is Luke’s other best friend and he is the marketing director for the winery. The men have been running the winery for the last year or so. Charlie likes Ali and so does Luke, so he hires her. Charlie is into reptiles and he also makes Ali make a grilled cheese sandwich for his snack. Hunter comes in the kitchen to tell them that the winds have shifted and there are wildfires nearby. All the roads in or out of the valley are closed down for now. Ali is stuck at the winery with the men and Charlie. Interesting dynamic between the three best friends. I loved that being stuck at the winery inspired Ali to start painting again. I enjoyed the story. I received a free copy of this book via Booksprout and am voluntarily leaving a review.

So So Good
Format: Kindle
I received this book with the understanding that I could leave a voluntary and honest review. In this book we meet Ali Firfax, Luke Ashford, Beckett Montgomery, & Hunter Jones. Ali is ready for a new adventure in her life. Though her mother worries about her she is determined to do her own thing. When she gets to the house though she can't believe how attractive all the men who live there are. Luke's first priority is defiantly his son, one look at Alit though has him wondering if he has been to narrow minded. When he two roommates realize who Ali is they will do anything they can to keep her there. When mother nature tends to help them they know they will do anything to keep her. Can they all find a HEA or will mother nature make sure none of them have a future? Amazing story by this author. I would highly recommend it to anyone.
