Pacemaker Full 2.5" Performance Exhaust System with Tri-Y Headers & Hi-Flow Cats for Holden VY Series 2 & VZ Station Wagon (5.7L Gen III V8) - Rear Pipe Only Layout - PP5367-33

Unleash devastating low-to-mid range torque, optimize scavenging velocity tracking, and extract a raw, track-inspired muscle car bark from your engine block with the Pacemaker Sport Systems full 2.5-inch performance exhaust solution featuring high-efficiency Tri-Y tuned extractors. Specifically configured to maximize power curves on Holden 5.7L Gen III V8 station wagon architectures, this premium package pairs race-bred performance hardware with an aggressive, straight-through rear section design. Custom-molded specifically to match the station wagon floor pan lines, clear elongated family wheelbase chassis structures, and map perfectly around vehicle-specific rear cargo floor structures, it completely eliminates power-robbing backpressure under wide-open throttle transitions. This track-biased version features a specialized 'Rear Pipe Only' layout configuration that deletes standard rear restrictive mufflers, completely opening up your vehicle's external sound fields. As Australia’s premium exhaust innovator, Pacemaker combines this heavy-hitting flow with 3" metallic high-flow catalytic converters and heavy-duty Tri-Y primary runs, generating an uncompromising acoustic statement when accelerating while ensuring straightforward, direct bolt-up compatibility underneath your performance wagon platform.

Note: Fits Holden VY Series 2 and VZ Station Wagon variants built from August 2003 onwards equipped with the 5.7L Gen III V8 engine layout; does not fit Sedan, Utility (Ute), One Tonner, or later generation VE/VF platforms due to significant chassis length, structural floor contour, and hanger position variations.

Features:

Precision-manufactured in Australia to deliver a heavy-duty high-flow upgrade, exceptional structural longevity under intense heat, and a raw, track-biased performance acoustic profile.

  • Complete Performance Kit: Comprehensive track performance upgrade incorporating premium tuned Tri-Y headers, 3" high-flow metallic catalytic converters, and a matching full 2.5-inch performance intermediate-to-rear layout path.
  • Tuned Tri-Y Design Architecture: Secondary-paired pipe layout engineered specifically to build exceptional low-to-mid range torque response, making it the perfect upgrade for heavy family wagon chassis acceleration tracking.
  • Rear Pipe Only Configuration: Stripped-back straight tailpipe construction deletes the rear mufflers to maximize volumetric gas velocity while establishing an exceptionally loud, crisp, uncompromised V8 acoustic bark.
  • Wagon Specific Clearance: Custom-tailored plumbing path configured to route cleanly beneath elongated wagon floor contours, deep rear cargo bays, and vehicle-specific station wagon chassis lines.
  • Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue.
  • High-Flow Mandrel Bent Tubing: Rigid full 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent flow restriction.
  • 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 Holden Commodore VY Series 2 and VZ Station Wagon configurations powered by the 5.7L Gen III V8 engine layout.
  • Wagon Specific Geometry: Designed strictly to conform around traditional VY/VZ wagon floor pan paths, rear floor load areas, and specific rear chassis hanger anchors. It will not adapt to Sedan, Utility (Ute), One Tonner, or later generation VE/VF wagon platforms due to major structural blueprint layout and length differences.
  • Acoustic Profile Note: This specialized setup features a straight-through rear pipe configuration with no rear acoustic muffler boxes. It will generate an exceptionally aggressive, highly pronounced V8 racing tone that is significantly louder than muffled sports applications.
  • Direct full bolt-up architecture interfaces seamlessly with original vehicle-specific rubber hanger brackets. No custom modification or cutting layout mapping is required.
  • Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, check steering column tolerances, verify proper pipe routing, and ensure completely gas-tight structural seals under the floor pan.

Wow!
Format: Kindle
This book was awesome! Seraphina and her family have moved to a new town. Her family is a bit... odd. She grew up learning how to protect herself from people who might hurt her. Bloodshed is a daily occurrence with her brothers and parents during their practice sessions, and it’s all fun and games unless you need to hide a body. Sera’s family is very close, and she’s been homeschooled most of her life. But in this new town she is going to start regular school as a senior at the local high school. Unfortunately, things at her school aren’t all they seem to be. Or perhaps more than they seem to be. Sera has her own demons to deal with, and she’s terrified her new friends will learn about her weird family and other issues and drop her like a rock. It turns out they have their own secrets as well. This story ends on a bit of a cliffhanger and I can’t wait to read the next one! This book is well written and well edited. The heroine is spunky and has a great heart and wicked sense of humor.

Great start
Format: Kindle
I loved this book! It's funny but still deals with tough themes, like chronic illness, a serial killer on the loose, and a dash of self-harm. The guys are interesting and distinct, we don't know too much about them yet. It does end on a really terrible cliffhanger but on the bright side the next book is out and I believe the series is complete. I have enjoyed both of these authors separately and this is a great team up!

Fudge!
Format: Kindle
Titles aren’t my strong suit. Sorry not sorry. That ending has me completely frustrated book two isn’t out yet. Just throwing that out there. First thing first, this is a high school book where the lead is under 18. Yea yea she’s about month from being an adult, but I can’t say I would’ve even opened the file if I’d realized. It’s not a smut fest or anything, but there is sexual tension as each party figures out their emotions. That being said, it’s a good book. There are some troubling parts, like how the supes come into their powers at 13, but most of those are dealt with in a way that makes sense. Kian is the exception. His whole arc pisses me off, especially since no one stepped in. Reflecting back on real world situations, ten or so years ago, I can see it happening, but it still makes me sick. Which, I’m sure was the whole damn point. For the most part, Courting Darkness is a fun read. I found myself laughing along with most of the set up. By the time it started getting serious, I’d grown to like the characters enough it held an impact. I’ll be adding book two to my list for when it comes out.

An intriguing story that played out slowly while introducing some unique characters. The story became quite fascinating to read as these same characters provided startling revelations to their lives. As their relationships evolve, more drama and mystery is revealed adding to my fascination. I can’t wait to read more.

Outstanding Story!!!!!!!
Format: Kindle
Oh I loved this story. Sera is such an amazing, fun character. She has so much fire inside of herself. She has humor that makes you laugh with her sassy comments. The guys are fantastic. I don’t feel as if we really have gotten to know who and what they are but they are such a mix of fae. The story is extremely well written and developed. It had me pulled in and didn’t let go. There was so much action, drama, and suspense. Then we get to the ending and goodness there is so much going on. This ending was a major cliffhanger and I absolutely can’t wait to see what happens next.
