Akrapovic VS Borla VS Kreissieg

This is what typical Akrapovič, Borla, and Kreissieg exhaust layouts might generally look like and focusing on their distinct characteristics. 

These aren’t exact blueprints, but they help visualize differences in muffler shape, piping style, and valved vs non-valved design.

🏁 1) Akrapovič (Sport/Titanium Style)

Akrapovič systems often have large dual-chamber mufflers with smooth bends and sleek tips.

     | AKR |   | RES |      ||   ||

     ╚═════╝   ╚═════╝

• O = pipe connection
• Big chambers, usually titanium or high-grade SS
• Often smooth bends for max flow

🚀 2) Borla (S-Type Sound Tech)

Borla is known for S-Type mufflers — a serpentine flow path for tone control.

• Balanced performance + tone

🔥 3) Kreissieg (Race-Focused Titanium)

Kreissieg systems often have straight-through flow with minimal muffling and larger diameter — very performance oriented.

• Long straight pipe sections
• Minimal internal baffling
• Designed for maximum flow and low weight

🧠 How They Compare Visually

Brand	Muffler Style	Flow Type	Sound Tendency
Akrapovic 	Big dual chamber	Smooth bends	Refined yet aggressive
Borla	S-Type serpentine	Balanced baffling	Rich and controlled
Kreissieg	Straight / race	Minimal restriction	Loud & track-oriented

📌 Notes

• Real exhausts are 3D bent pipes, not flat like ASCII, but this gives a conceptual idea.
• Tailpipe count, diameter, and angle vary by model (e.g., 2× vs 4× tips).
• Valved systems (common on Akrapovič/Armytrix) add valves near the muffler — you could imagine a “little box” in the piping.

The EA888 family and their advantages

 

🛠️ Overview: What Is the EA888?

The EA888 is Volkswagen Group’s modular 4-cylinder turbocharged petrol engine used across VW, Audi, Skoda, Seat (and even some Porsche models). It’s popular for its balance of performance, fuel economy, and tuning potential — making it a go-to engine for hot hatches and sporty sedans. 

🔁 How Many EA888 Versions Today?

In broad terms, there are four main generations still in use today:

1️⃣ EA888 Gen 1 / Gen 2

• Early versions (~2008–2013)
• Introduced TSI turbo + direct injection and chain timing (vs older belt engines)  
• Power ~170-220 hp depending on tune
• Used in early Mk5/Mk6 Golf GTI, Jetta, Passat, A3/A4, etc.  

👉 Edge over rivals back then: More modern tech (direct injection + turbo) than many competitors that were still using naturally-aspirated or older turbo engines.

2️⃣ EA888 Gen 3

• Most common in cars built ~2013–2020  
• Major upgrades:
  ✔ Dual variable valve timing
  ✔ Integrated exhaust manifold for faster turbo spool
  ✔ Dual injection (direct + port) on many variants (better emissions/efficiency)  
• Power ranges from ~210 hp up to ~310 hp in high-output “3B” versions  

Used in models like:

✅ VW Golf GTI Mk7

✅ VW Golf R (Gen3 versions)

✅ Audi S3 & A3 8V

✅ Skoda Octavia RS

✅ Seat Leon Cupra

✅ Tiguan, Passat, Jetta GLI (varies by market) 

👉 Edge: Tunability and power potential. The Gen3 is beloved in the aftermarket and enthusiast community because it responds well to tuning and hardware upgrades.

3️⃣ EA888 Gen 4 (aka “EVO4”)

• Debuted around 2020 and later cars  
• Focused on emissions, efficiency, refinement
  ✔ Updated combustion, timing, thermal management
  ✔ Some markets include particulate filters (GPF)  
• Power similar to Gen3, but details vary by tune and market  

Common current fits:

✅ VW Golf Mk8 GTI / Golf 8 R

✅ Audi A3 / S3 8Y

✅ Passat (facelift)

✅ Tiguan Mk2 (facelift)

➡️ Also used in some Atlas/Teramont and other MQB-based cars. 

👉 Edge: Better real-world fuel economy, lower emissions and smoother performance vs older EA888 engines.

4️⃣ EA888 Gen 5 (Emerging)

• Latest evolution rolling out in new vehicles for ~2025+ models (e.g., Tiguan) with improved turbo tech and higher power.  
• This is still very new and expanding into more models.

Edge (so far): More power and efficiency, but long-term reliability is still being evaluated.

🧠 How EA888 Compares to Rivals

Strong points:

• Excellent power-per-liter thanks to turbo + direct injection
• Very tunable for performance builds
• Widespread parts availability because the engine is used in many models
• Improved thermal management and emissions over older designs

Weak points (historically):

• Early generations had oil consumption and tensioner issues (less so in Gen3/4)
• Gen4 has slightly less aftermarket support (because it’s newer)  

🚘 Summary: Which Models Use EA888

Here’s a snapshot of the main cars with EA888 engines (varies by region/year):

• VW: Golf GTI, Golf R, Jetta GLI, Passat, Tiguan, Atlas/Teramont
• Audi: A3 / S3 / TT / Q3 / Q5 (varies by year)
• Skoda: Octavia RS, Superb, Kodiaq
• Seat/Cupra: Leon Cupra, Ateca Cupra, etc.  

 

APR Carbon Fiber Wind Splitter With Rods - Honda Civic Type R W/ Factory airdam 2017 - up SKU: CW-917022

Here’s the main benefit of the APR Carbon Fiber Wind Splitter With Rods (SKU: CW‑917022) for a Honda Civic Type R (2017-up) with factory airdam:

🚗 What It Does & Why It Helps

Improved Aerodynamic Performance

• This carbon fiber wind splitter reduces front-end lift by creating a high-pressure zone above the splitter and lower pressure beneath the car. That means the front tires stay more planted to the road at speed, which can improve traction and control.  

More Stability at Higher Speeds

• By reducing lift, you gain better stability when accelerating or driving fast down straights, and improved confidence when approaching corners.  

Enhanced Control & Cornering

• With extra downforce up front, your car can feel more balanced and predictable through braking and turns — useful if you’re driving aggressively or on a track.  

Functional Design (Not Just Looks)

• It fully covers the area under your front bumper, smoothing airflow and maximizing aerodynamic efficiency rather than just being for appearance.  

Lightweight & Durable

• Made with carbon fiber and reinforced for strength, the splitter adds performance benefits without a big weight penalty.  

Comes With Support Rods

• The included rods help keep the splitter rigid and stable at high speeds, preventing flex that can reduce effectiveness.  

Summary:

The APR carbon fiber wind splitter mainly improves high-speed stability, traction, and aerodynamic efficiency on a Honda Civic Type R with a factory front airdam, especially during spirited driving or performance use.
