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.

BEST PILLOW OUT THERE! Great for back and side sleeping. So glad I found them!
Like a cloud! Really loving this pillow set! I have tried many different pillows trying to get rid of my neck pain to no avail. One of the pillows even had a chiropractor endorsing it - and then I found it was actually causing me jaw pain when I slept on my side because it was too firm and had no give. We are LOVING THIS CERVICAL NECK PILLOW! I have been using it consecutive nights as a back sleeper and side sleeper and my neck continues to feel pain-free, no cricks and when I sleep on my side there is no pressure on my jaw or shoulder pain. It has just enough support in all the right places and enough give in the center to allow my head to comfortably sink into the middle aligning my neck for comfort, and enough give it does not put pressure on my jaw from the side sleeping. It also came with 2 pillow cases that are soft - I love the way it keeps the frizzy of hair from developing around my face because my hair is sliding, rather than friction when I move in my sleep. This pillow is a Win-Win! Getting a set for my son too!

Great Pillows, But Made for Taller People
Clearly these pillows are high end, very well-made pillows that will last for, dare I say, decades, and they are supportive for the neck and spine... for some people. I got the set of two, one for myself and one for my husband. I am 5'4", about 165lbs, and he is 6'2" about 240lbs. So there is a big difference in size between us.
The pillows arrived in a very small but high quality box, each rolled separately, and I thought for sure that they would take a while to roll out, fluff up, and unwrinkle, the way our bed and other pillows did. But that wasn't the case at all. These pillows immediately fluffed up and were usable with not a single wrinkle (see photos). The silk gray cases that come with them were also in no way wrinkled and fit like a glove. They were a little difficult to situate for me (the cases) because they must go on a certain way (my husband wants me to tell y'all that he got it right the first time). It took me three tries. But once they were on, they looked beautiful and the pillows felt very soft with them on.
Now, that said, it was clear the moment I laid on it that it's made for someone taller, or rather, with a longer neck. When I lay on it, my head does not land on the center of the pillow where the bump is, where it's supposed to cradle my neck. My head instead lays directly on that bump, cocked up with my neck kinked. That's also because *I* am a side sleeper. Now if I lay on my back, my head lays a little more in the center. That is the only way this pillow slightly works for me. If you read the "instructions," it explains that there is a section for your head when you're laying on your back (the center dip) and a section for when you're on your side (the edges). Either way is too high for me. My neck isn't long enough. In order to get it into the correct position, I have to stretch it unnaturally. When I lay naturally, my neck is bent and kinked and hurts more in the morning than ever before.
The feel of it, putting aside its side and dimensions, is very soft to the touch but also quite firm at the same time. It's not the kind of memory foam that takes a while to bounce back. It's bounces back immediately. It's very springy.
The only way I can use this pillow is if I spin in around to keep the cervical support bump at the top and just lay over the flat portion, making it more like a regular pillow. It's still too high and stiff for me, but it's better.
Now for my husband (6'2"), this pillow works great! He's a back sleeper and it really supports his neck. And he does sometimes lay on his side, and apparently it's supports his neck then too. His neck is long enough to reach that edge section for side sleepers and the center supportive dip for back sleepers. He loves it! He says, his neck feels great in the morning and it's his new favorite pillow.
When I got this pillow set, it was listed at $340, and he said that it was not worth that price. But it is now listed at $169, and he's saying that is a much more reasonable price. I personally wouldn't pay that, but that's because the pillow doesn't work for me. I stand by my statement that these pillows are for taller people (or people with longer necks). But for him, he would pay it. I wish it worked for me. I'm a bit jealous, to tell you the truth.

Finally, a pair of pillows that look good on the bed and feel good on the neck.
As much as I like the comfort and support of a cervical neck pillow, they usually have a strange ufo-type look and are usually quite small. It's fine for use, but they are not a great look on the bed. I wanted something more welcoming and full-looking with the support of a c-pillow. This set actually met my hopes and needs.
I love how the pillow has two strengths - firmer on one side, softer on the other. That makes it easy to find the best fit for your own neck shape and support needs. The pillows are large enough that side-by-side on a queen sized bed they look welcoming and like they could probably even have matching cases put on them instead of requiring specialty industrial-looking pillow cases like many do.
Having proper neck support has reduced headaches and neck tension and allows for better sleep!

Perfect if you're in the right position, not so perfect otherwise
I've been using this for about a week and I like it, but with some caveats. It is shaped so you can only sleep in 2 positions and you can't really move in bed. As long as you are in the correct position, it is really comfortable and provides the best support you can ask for. The problem is if you move around in bed, it turns into a hinderance. With normal pillows, they more or less move with you and are comfortable as you move. This is very specifically great in a single position, but terrible in any other position. If you are able to keep still, this is the perfect pillow for you. If you are like me and roll around too much, its more of a problem for sleeping than a help. I am going to move it over to my couch for napping with, and I think it'll work out far better since the couch isn't really big enough to roll around.

Great quality
Size: Twin, Color: White
This mattress pad is just thick enough without being overly bulky which tends to bunch up after washing. It is super soft and fits twin bed perfectly with just enough padding to add comfort. For a waterproof cover this one is superior to others I've had.
