Review HONDA 79-80s Exhaust fits CB750

The **Honda CB750 exhaust system** from the late 1970s specifically the models produced between **1979 and 1980** represents a classic and highly sought-after component for both restoration and performance enthusiasts. This era of the legendary CB750 marked a transitional period where Honda refined its iconic four-cylinder design while maintaining the timeless appeal that defined the machine. The exhaust system from these years is a meticulously crafted assembly, blending durability with a distinctive, throaty growl that has become synonymous with the CB750 s character. Crafted from high-quality **mild steel tubing**, the exhaust features a **dual-into-single** configuration, a hallmark of the era, which not only enhances the bike s aggressive sound but also contributes to its classic aesthetic. The **primary pipes** are polished to a mirror finish, showcasing the precision welding and machining that were standard in Honda s manufacturing during this time. The **mid-pipes** are often left in their original matte black finish, adding a touch of vintage charm, though some aftermarket options may offer chrome or custom finishes for a more modern look. The **exhaust headers** are designed with a slight taper, optimizing airflow while maintaining structural integrity, and the **mufflers** are robust, featuring a **heat-shielded construction** to protect the surrounding components from excessive heat buildup. One of the most distinctive features of the **1979-1980 CB750 exhaust** is its **clamp-style mounting system**, which ensures a secure and vibration-dampened connection to the bike s frame, reducing fatigue over time. The **silencer design** from this period is slightly more aggressive than later models, producing a deeper, more resonant tone that enthusiasts often describe as "muscular" and "authentic." Whether used in a fully restored classic or as a standalone upgrade for a modern CB750, this exhaust system embodies the spirit of the era where performance, reliability, and timeless design converged to create one of the most influential motorcycles of all time. For collectors and riders alike, owning a genuine **1979-1980 CB750 exhaust** is not just about maintaining authenticity; it s about preserving a piece of automotive history that continues to inspire generations of motorcycle enthusiasts.

### **Pros and Cons of Buying a 1979 1980s Honda CB750 Exhaust System**

The exhaust system on a 1979 1980s Honda CB750 is a classic component with several advantages for enthusiasts and restorers.

1. **Vintage Sound and Character** The original exhaust produces a deep, throaty growl that is highly sought after by motorcycle purists. The design, featuring dual exhaust headers and a single muffler, contributes to the bike s iconic 1970s 80s tone, which many riders find more engaging than modern, louder systems.

2. **Historical Authenticity** For restoration projects, using period-correct exhaust ensures the bike retains its original appearance and mechanical integrity. This is particularly important for show bikes or those intended for classic motorcycle events where authenticity matters.

3. **Durability (When Properly Maintained)** Early CB750 exhaust systems were built to last if cared for. The stainless steel headers and mild steel mufflers, though prone to rust over time, can be restored or replaced with high-quality replicas. Many original systems still function well if cleaned and treated against corrosion.

4. **Ease of Modification** The CB750 s exhaust is relatively straightforward to modify. Aftermarket headers, mufflers, and complete exhaust systems are widely available, allowing riders to experiment with sound, performance, or compliance with modern emissions regulations.

5. **Resale Value for Classics** If the bike is in good condition, an original or well-maintained exhaust system can enhance its appeal to collectors and classic motorcycle buyers. Restored original parts often command a premium in the vintage market.

6. **Simplicity in Installation** Compared to modern systems, the CB750 s exhaust is relatively easy to install or replace, even for DIYers. The design is simple, with fewer components than later models, reducing potential points of failure.

7. **Compatibility with Aftermarket Parts** The CB750 s exhaust design has been around long enough that aftermarket manufacturers produce replacements, upgrades, and custom exhausts that fit seamlessly. This includes everything from mild performance upgrades to full custom builds.

While the original exhaust has its charms, there are several drawbacks to consider, especially for daily riders or those seeking modern performance.

1. **Rust and Corrosion** The most significant issue with older exhaust systems is rust. The mild steel mufflers and headers are susceptible to oxidation, especially in wet or salty climates. Rust can weaken the structure, leading to leaks, cracks, or even catastrophic failure if ignored.

2. **Poor Emissions Compliance** Modern exhaust systems are designed to meet emissions standards, which the original CB750 exhaust does not. Riding an unmodified classic bike in many regions may result in fines or registration issues, particularly if the bike is used on public roads frequently.

3. **Noise Levels** While the sound is desirable to some, the original exhaust is extremely loud by today s standards. Many states have strict noise regulations, and riding an unmodified CB750 could lead to complaints from authorities or neighbors. Aftermarket mufflers or modern exhausts are often required to meet legal limits.

4. **Performance Limitations** The original exhaust is not optimized for modern performance standards. While it may sound great, it does not provide the same flow efficiency as later or aftermarket systems, which can affect throttle response and power delivery, especially on high-performance builds.

5. **Maintenance Requirements** Rust and wear mean that the exhaust system may require frequent inspections, cleaning, and potential replacements. This adds to the ongoing cost of ownership, particularly for daily riders who cannot afford to neglect maintenance.

6. **Limited Availability of Original Parts** While aftermarket parts exist, finding genuine OEM exhaust components for a 1979 1980 CB750 can be difficult. Prices for original parts may also be high due to their age and collectibility.

7. **Weight and Durability Concerns** The original exhaust system is heavier than modern alternatives, which can affect handling and fatigue over time. Additionally, the materials used in the 1970s 80s were not as advanced as today s stainless steel or high-temperature alloys, making them more prone to wear.

---

The original or period-correct exhaust system on a 1979 1980 Honda CB750 is a fantastic choice for **restoration projects, show bikes, or riders who prioritize vintage authenticity and sound**. It offers a unique character that modern exhausts cannot replicate and is relatively easy to work with. However, for **daily riders, performance-focused builds, or those in areas with strict emissions and noise laws**, the original exhaust may not be practical. Rust, noise, and compliance issues can make it a liability rather than an asset.

If you plan to keep the bike as a classic or for occasional rides, the original exhaust is worth preserving. If you intend to use the bike regularly or modify it for performance, investing in a **modern stainless steel exhaust system** (while still maintaining a vintage look) is a more practical choice.

---

- **For Restoration or Show Bikes:** Retain or restore the original exhaust if possible. If rust is severe, seek out high-quality replicas or aftermarket period-correct systems to maintain authenticity.

- **For Daily Riding or Performance:** Replace the original exhaust with a **modern stainless steel system** that meets emissions and noise regulations. Brands like **Akrapovic, Speed Twin, or Yoshimura** offer excellent aftermarket options that retain a classic look while improving durability and performance.

- **For Sound Purists:** Consider a **mildly modified aftermarket exhaust** (e.g., a slightly larger muffler or custom headers) that enhances the vintage tone without violating noise laws.

- **For Rust-Prone Areas:** If the original exhaust is rusted, prioritize replacement over restoration. A new system will save long-term hassle and cost.

Ultimately, the decision depends on your priorities whether you value historical accuracy, practicality, or a balance of both. For most riders who want to enjoy their CB750 regularly, a well-chosen aftermarket exhaust is the best compromise.

Details:

I do believe these are original. If you want these shipped, you'll have to pay the cost. They do sound how these should. These could use a shine to make them look nicer.

They also look as if they were repaired in the bottom with muffler seal/putty. These are a 4 into set. These came off a 1979 Honda CB750 Anniversary Addition bike.
