Borla Touring Cat-Back Exhaust System for 2018 Lincoln Navigator 3.5L V6 Twin Turbo Automatic Transmission Four Wheel Drive 4 Door. (140744)

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Features:

  • Horsepower and Torque Increased by 7 – 10%
  • Increased exhaust flow for better performance
  • Better fuel economy at cruising speeds
  • The most aggressive sound of any Borla system
  • Custom designed for each application
  • Patented straight-through, multi-core muffler design reduces backpressure while absorbing sound waves
  • Mandrel-bent stainless steel tubes with diameters optimized for reduced restriction while maintaining exhaust gas speed
  • Made from the finest austenitic stainless steel for long-lasting durability
  • All welded construction
  • Includes everything required for installation, including detailed instructions
  • Backed by the exclusive Borla Million-Mile warranty
  • Proudly made in the USA more

BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology designed to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

An absolute must for everyone dabbling with Unity 6 Game Development
Format: Paperback
Half of this book is about C# (until Chapter 6), and the other half is about actually making games. The book is very well written, and it is everything I needed to get a few problems solved with Unity 6 projects. I love how clearly things are explained, and the only thing I wish for is that I was able to spend more time delving into this while maintaining my financial status...

A Seasoned Developer's Fresh Perspective on Game Development
Format: Paperback
Finally, a game dev book that respects your existing programming knowledge As someone who's spent two decades architecting enterprise web applications in C# and ASP.NET, I approached game development with what I thought was a solid foundation. I was wrong—not about C#, but about how differently it's applied in game engines. After five frustrating years of trying to bridge that gap through scattered tutorials and documentation, Harrison Ferrone's eighth edition finally gave me the structured path I needed. What This Book Gets Right for Experienced Developers: The pacing is deceptive. Yes, it starts with programming fundamentals, but don't skip ahead. Ferrone's approach to OOP in the context of Unity's component architecture was revelatory. In web dev, I'd been writing services, repositories, and dependency injection for years. Here, the MonoBehaviour lifecycle and component-based thinking required a genuine mental shift that the book handles exceptionally well in chapters 5-6. Chapter 10's revisit of types and methods isn't redundant—it's strategic. By this point, you've written enough Unity scripts to appreciate why game code patterns differ from traditional enterprise patterns. The discussion of value types vs reference types hits differently when you're optimizing frame rates instead of HTTP response times. The Unity 6 Update Matters: Having struggled with outdated Unity tutorials for years, the Unity 6-specific content is invaluable. The screenshots are comprehensive (full-screen mode can make text small, but the GitHub repo and graphics bundle solve this). More importantly, the code samples reflect current Unity APIs and best practices, not deprecated approaches that still litter Stack Overflow. Where It Shines for Career Transitioners: Chapters 11-13 are worth the price alone. LINQ in Unity isn't just about querying collections—it's about performance considerations I never had to think about in web apps. The coverage of generics, delegates, and events finally connected how Unity's event system relates to patterns I already knew, but in a real-time context where every allocation matters. The serialization chapter (12) bridged my understanding of data persistence from databases and JSON APIs to Unity's PlayerPrefs and ScriptableObjects. This practical grounding is what most tutorials skip. Minor Quibbles: The FPS prototype is solid for learning, but I wish there was more discussion of common anti-patterns experienced developers bring from other domains. I still catch myself over-engineering solutions when Unity's component system offers simpler approaches. Also, while the book touches on performance, those coming from async/await-heavy web development will need supplementary resources on Unity's coroutines and the Job System for more complex scenarios. Bottom Line: If you're a professional developer trying to break into game development, stop collecting random Udemy courses. This book provides the structured progression and context-appropriate examples that respects your intelligence while teaching you to think like a game developer. The C# you know is necessary but not sufficient—Ferrone bridges that gap methodically. After years of false starts, I finally have a working game prototype and, more importantly, the mental models to keep building. That's worth significantly more than the cover price. Disclosure: I received an advance review copy from Packt Publishing. This honest review reflects my genuine experience as a career-changing developer.

A Worthy Touchstone for Anyone Who Wants to Master Unity
Format: Paperback
Harrison Ferrone’s Learning C# by Developing Games with Unity 6 is one of the strongest beginner-to-intermediate Unity guides I’ve read: carefully structured, patient in its explanations, and quietly packed with insight about how Unity 6 and C# truly work together. I read the physical edition while sitting in front of a blank Unity project, and the experience felt like having a seasoned sailor point out the currents of a river I’ve been navigating for years. You see the familiar terrain differently. The book’s early decision to spend real time on C# fundamentals is a welcome choice. Most Unity books skip past the language; Harrison slows down, defines concepts, and gives you enough clarity that when you finally enter Unity, you understand why things behave the way they do. Those chapters are dense in the best way: they prep beginners to stand on solid ground and give experienced users a clean, refreshed mental model of the language under the engine. Ferrone’s real strength is his voice. He strikes a balance I rarely see in technical writing: conversational introductions that explain what you’re about to learn and why it matters, followed by crisp, accessible technical walkthroughs. The pacing (explanation → example → implementation) is excellent. And the inclusion of ready-to-use assets removes one of the biggest barriers for new developers who want to understand systems without getting lost creating placeholder art. The book doesn’t talk down to anyone. It makes Unity feel more accessible without flattening its complexity. Beginners will come away with genuine competence; advanced users will appreciate the clear framing of new Unity 6 tools and the subtle recognition of how AI-assisted coding is shaping modern workflows. It’s a guide you can read once for understanding, then keep at your desk as a reference. If you’re a serious hobbyist, a technically inclined beginner, or someone who’s ready to work through your first real project, this is the Unity book I’d hand you first. It bridges concept and execution with clarity and confidence, and it does so with a tone that feels patient, practical, and quietly encouraging. In a space crowded with copy-paste tutorials, Harrison Ferrone has written a Unity 6 guide with real staying power.

Pretty good beginner book, very user friendly covers Development and Design
Format: Paperback, Format: Paperback
I enjoy learning Game Dev, but I research books because many authors promise a lot and deliver half or not at all and I have to put the book down. This book was pretty good. I appreciate the author explaining things, and remember he's writing a book for beginners. There's also a good amount of pics in the book, and I dislike a book with no pics. Also, he breaks it down very simply and explains that you're not going to learn the entire Unity ecosystem, but rather a beginner-level understanding to get a person started. I enjoyed this book and will definitely go over particular info again. They have a Discord group and a newsletter with tips and it also goes over Game Design. I was surprised to see this, and maybe it's new to me, and I like the analogy of explaining complex terms. A con of the book is that as it progresses, it starts to come off as advanced in scripting, and I turned to AI for additional explanations. Still, the author did explain in advance that it's about to get more advanced, but that's me going deeper into the meaning and explanations. Other than that, it's a good read that you will go to more than once and has practical info to help you on your Unity journey.
