Pacemaker 2.5" Performance Exhaust System with Tri-Y Headers & Rear Pipe Only for Holden WH-WL Statesman V8 - PP5367-18

Unlock the torque and an ultra-aggressive V8 bark from your 5.7L Gen III engine with the Pacemaker Sport Systems complete exhaust solution. Specifically engineered for the Holden WH, WK, and WL Statesman and Caprice luxury long-wheelbase platforms, this high-flow setup is configured with a high-volume "Rear Pipe Only" exit plan instead of a standard rear muffler assembly. This premium kit features precision-tuned Tri-Y headers for optimized low-to-mid range scavenging paired with a mandrel-bent 2.5" system. As Australia’s top manufacturer, Pacemaker utilizes signature engineering to deliver maximum exhaust gas velocity while providing a direct performance tone that stands out. Note: Fits Holden WH, WK, and WL models (1999–2006) equipped with the 5.7L LS1 V8 engine.

Features:

Precision-manufactured in Australia to deliver the ultimate balance of heavy-duty flow efficiency, raw acoustic output, and long service life for the long-wheelbase Holden platform.

  • Complete Headers Setup: Total kit featuring high-performance Tri-Y 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.
  • Tri-Y Extractors: Specifically optimized to maximize mid-range torque delivery and sharpen throttle response on LS1 platforms.
  • Premium Materials: Constructed using top-tier Exhaust Grade 409 Stainless Steel for excellent service life.
  • Mandrel Bent Tubing: 2.5" (63mm) 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.

Great product
Color: Purple, Color: Purple
My dogs loved these toys. Durable and apparently very coveted as my puppers “argued” over who got each one. Kept them playing and chewing for hours. Giving only 4 stars instead because I Wish the size was bigger because I have found that sometimes I don’t see it and stepping on it is Absolutely NO FUN.

Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26
