Pacemaker Heavy-Duty 3" Performance Cat-Back Exhaust System for Ford Mustang GT Convertible (5.0L Coyote V8) - PP4178-52
Unleash a deep, aggressive American muscle growl and unlock massive flow capacity from your high-revving quad-cam engine with the Pacemaker Sport Systems heavy-duty large-bore 3" performance cat-back exhaust solution. Specifically engineered to maximize scavenging efficiency and satisfy the high-velocity gas volume demands of the iconic 5.0L Coyote V8, this premium system is precision-molded to clear the specific underbody bracing lines and structural layouts unique to the S550 soft-top architecture. By replacing your stock, restrictive factory plumbing with a high-volume mandrel-bent performance construction downstream of the catalytic converters, it optimizes gas velocity to clear spent exhaust out rapidly and completely eliminate power-robbing backpressure under acceleration. As Australia’s premium exhaust innovator, Pacemaker pairs this high-flow path with patented V-Tex technology and signature double-skinned mufflers to deliver a raw, thumping muscle car sound outside while actively engineering out harsh, intrusive interior cabin boom or open-air highway drone typical of convertible cabins. Note: Fits Ford Mustang GT S550 Convertible models (2015–2017) equipped with the 5.0L Coyote V8 engine configuration; engineered with optimized global clearance metrics to suit both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) configurations.
Features:
Precision-manufactured in Australia to deliver a premium flow upgrade, exceptional structural durability under high heat, and a refined performance acoustic profile for the global Mustang GT platform.
- True 3" Cat-Back Section: Complete high-volume performance intermediate plumbing and rear muffler layout engineered to bolt up securely behind your factory or high-flow catalytic converters.
- Convertible-Specific Clearances: Custom engineered to route flawlessly around the additional under-car chassis strengthening cross-bracing unique to the soft-top convertible floor pan.
- Dual Drive Layout Compatible: Precision-cleared underbody routing architecture engineered explicitly to accommodate both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) chassis variations.
- Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity under intense thermal stress.
- Mandrel Bent Tubing: Rigid large-bore 3" (76.2mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to optimize exhaust gas velocity and prevent restriction.
- V-Tex Technology: Advanced internal anti-drone configuration filters out harsh, low-frequency cabin resonance typical of open convertible cabins without creating any power-robbing flow restrictions.
- Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case protection, zero internal packing blowout under high thermal stress, and precise tonal control.
- 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.

Influencers writing books...
Format: Paperback
First off, if you really want to read a great book on plasma and consciousness, read Robert Temple - A New Science of Heaven. Everything is in there. Extremely well written and easy to follow. Less than half the price too for an actual book. If you then go with that understanding into the peruvian jungle you'll be fine.
Now, this one here is a different matter altogether:
Format
650+ pages(!) of poorly formatted and poorly written text. The book is physically humongous too! Why?
Constant text breaks and list type snippets make it hardly readable. This whole package could have been packed into half the amount of book. More is not better in this instance. Flow and framing is bad and superficial. It feels and reads like she is just listing things like in a high school essay rather than actually exploring the topic. Reminds me of internet bros that create these lists of stuff and think by just collecting and listing things, meaning and relevance emerges automatically. It doesn't. A good book knows flow and framing and takes the reader by the hand- not just stating or claiming things without proper context, real proof and relatability.
Relevance
Why is she in a position to talk about plasma and consciousness?
She had a difficult life and then meditated twice(!) and all of a sudden she is an expert on plasma consciousness? No framing in any of the chapters. Just blank statements and made up words that she trademarked. Not only one but at least three! How does she know these things? No personal examples or believable context. She basically says "here x-person said this - now I say that" Why? no one knows. Where is the proof and experience in what she says?
It's just loosely collected snippets of words and sentences that lack context and relevance. Example: The Kordilevksy clouds are located at the lagrange L4 and L5 points. No explanation what that really is. I'm sure most readers are not familiar with lagrange points. Or, anyone know what Tubulin Dimers are? What Dipoles are? "The sun maintains structural and rhythmic coherence via electromagnetic resonance" Really? How? why? Ah yes ,that explains and equates naturally with "when thoughts and emotions align, you enter a flow state" sure. ok. if you say so. Tons of examples like this.
Finally, apart form generic templates, simple "pay attention to this type exercises" and archetypal concepts and pretty meaningless 3d,4d 5d nomenclature, it completely lacks a "how to". How can one become a plasma being? Like, actually in real life? How does a life look like that is lived as a fully conscious and aware plasma consciousness? I guess I need to go onto her website and buy some of these trademarked programs.
Mabye, there is a reason why sages over the millennia have dedicated entire lifetimes to fashioning themselves and learning about themselves and their plasma beingness? If this was instagram easy through 2 meditations I'd like to know THAT secret. The sages of old have gone through long and arduous journeys to completely transform themselves and their bodies with years of yoga, qigong and psychedelics aka alchemy into said plasma beings. Some very few and far between just struck by cosmic plasma consciousness without really doing much. However, I don't find the evidence for either process having taken place with the author.
Conclusion
Overall, this book is a pretend in my opinion. She hides behind empty words that create the appearance of knowingness without being accurate, in-depth and in-detail, based on her own actual experiences with the matter. Fast social media marketing with typically inflated prices for low quality content, because "they are worth it".

A big, beautiful, gift of a book!!
Format: Paperback, Format: Paperback
I hadn’t even made it past the intro before I had to email Dana and thank her for this book. THAT is the energy this book contains.
Her heart-centered distillation of LOTS of research and knowledge connects the dots so effortlessly and joyfully.
It seems every time I pick up this book I feel inspired, smarter and connected to it ALL!
This book is a gift!

Book content good but formats for both kindle and hard copy versions are not as expected
Format: Paperback, Format: Paperback
The info in the book is good however I originally purchased the kindle version but the format was difficult to read. It’s not like a regular kindle book. The book was beautiful and the pictures inside were in color.
So I decided to go ahead and order the hard copy even though it was very expensive. I received it today and it’s in all in black and white. No beautiful colored pictures.
For $45 it should be in color like the sample or kindle version. I spent $55 for both versions and neither is what I expected format wise. Just disappointing. It would be 5 stars of these issues were fixed. I attached a page of the kindle vs paperback.

The Best Fluoride-Free Toothpaste I've Tried
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
I've been using Davids Hydroxi Fluoride-Free Nano Hydroxyapatite Toothpaste for several weeks, and it has completely exceeded my expectations.
The first thing I noticed was how clean and smooth my teeth felt after brushing. Unlike many natural toothpastes, it leaves a genuinely fresh feeling without being overly harsh. The natural peppermint flavor is refreshing and pleasant without the intense burn that some mint toothpastes have.
What really impressed me is the nano-hydroxyapatite formula, which is designed to support enamel remineralization and reduce sensitivity. My teeth have become noticeably less sensitive to cold drinks, and they feel stronger overall. Nano-hydroxyapatite is gaining attention as a fluoride alternative because it can help replenish minerals in enamel and reduce sensitivity.
I also appreciate that it's:
Fluoride-free
SLS-free
Made in the USA
Vegan
Uses high-quality ingredients
Comes in a recyclable metal tube
The whitening is subtle but effective. My teeth look brighter without any increased sensitivity, and the toothpaste is gentle enough for daily use. The inclusion of xylitol and hydroxyapatite makes it feel like a premium oral care product rather than just another natural toothpaste.
While it's more expensive than conventional toothpaste, the quality and ingredients justify the price. Even dental professionals reviewing hydroxyapatite toothpastes have noted benefits for remineralization, sensitivity relief, and plaque reduction.
Overall: 5/5 stars. If you're looking for a fluoride-free toothpaste that supports enamel health, helps with sensitivity, and leaves your mouth feeling exceptionally clean, Davids Hydroxi is absolutely worth trying. Highly recommended!
