For the Honda CB650R, a new exhaust is the quickest path to a deeper, more refined inline-four sound. Finding the best exhaust for honda cb650r can be tricky because there are so many options. This guide will help you pick the right one for your bike and your budget.

Your CB650R already sounds good stock, but it’s quiet. A good exhaust wakes up the engine’s character. You get more power, less weight, and a sound that turns heads.

We tested and researched the top exhausts on the market. We looked at sound, performance, fitment, and price. Here is everything you need to know.

Why Upgrade Your Cb650r Exhaust?

The stock exhaust on the CB650R is heavy and restrictive. It muffles the beautiful inline-four note. Replacing it does a few things.

Weight savings: Stock systems can weigh over 15 pounds. Aftermarket options can cut that in half.
Better sound: You get a deeper, more aggressive tone without being obnoxious.
Performance gains: Most exhausts add 3-5 horsepower with a proper tune.
Looks: A sleek slip-on or full system changes the bike’s appearance completely.

This section covers the top contenders. Each exhaust has its own strengths. We break down what makes each one special.

Akrapovic Exhaust Systems

Akrapovic is a premium brand. They make high-quality systems for the CB650R. Their slip-on and full systems are popular.

The Akrapovic Racing Line slip-on is a top seller. It uses titanium and carbon fiber. The sound is deep and refined, not too loud. It saves about 4 pounds over stock.

Installation is straightforward. You remove the stock muffler and bolt on the Akrapovic. No cutting or welding needed. The fitment is perfect.

For full systems, the Akrapovic Evolution Line is the best. It includes headers and a muffler. This gives you the biggest power gains. You will need a ECU flash to get the most out of it.

Yoshimura Exhaust Options

The Yoshimura AT2 has a unique oval shape. It sounds aggressive but not too loud. The build quality is excellent. It comes with a removable baffle for sound adjustment.

The R-77 is a classic round canister. It has a deeper tone than the AT2. Both options save weight and improve throttle response. You can install them at home with basic tools.

SC Project Exhausts

SC Project makes loud, race-inspired exhausts. They are popular for their raw sound and Italian styling. The CR-T and S1 are the most common.

The SC Project CR-T is very short and stubby. It produces a loud, aggressive bark. This is not for quiet neighborhoods. It saves significant weight.

The S1 is slightly longer but still loud. It has a more refined tone than the CR-T. Both systems require a baffle insert for street use in some areas. Check local noise laws.

Two Brothers Racing Exhaust

The M-2 is a classic oval shape. The M-5 is more modern and angular. Both have a deep, throaty sound. They are louder than stock but not obnoxious.

Slip-On Vs Full System: What To Choose

You have two main choices: slip-on or full system. Each has pros and cons. Here is a breakdown.

Slip-On Exhausts

A slip-on replaces only the muffler. It is the easiest and cheapest upgrade. You keep the stock headers.

Pros: Lower cost, easy install, good sound improvement, no tuning needed.
Cons: Less weight savings, smaller power gains, stock headers remain.

Most riders start with a slip-on. It gives you the sound you want without major work. You can install it in under an hour.

Full Exhaust Systems

A full system replaces everything from the engine to the tip. This includes headers and muffler. It is more expensive but offers bigger benefits.

Pros: Maximum weight savings, biggest power gains, better looks.
Cons: Higher cost, harder install, usually requires ECU tuning.

Full systems are for riders who want the best performance. You will need a power commander or ECU flash. This adds cost but unlocks real horsepower.

How To Install An Exhaust On Your Cb650r

Installing an exhaust is a DIY job. You need basic tools and patience. Follow these steps.

Gather tools: You need sockets, wrenches, and a torque wrench. Have penetrating oil ready for rusty bolts.
Remove stock exhaust: Unbolt the muffler from the mid-pipe. Loosen the header bolts at the engine. Slide everything out.
Install new system: For slip-ons, attach the new muffler to the stock mid-pipe. For full systems, install headers first, then the muffler.
Tighten bolts: Use a torque wrench to spec. Do not overtighten. Check for leaks after starting.
Test ride: Listen for rattles or leaks. Recheck bolts after a few rides.

Most installations take 1-2 hours. Full systems take longer. Watch a video guide for your specific exhaust.

Sound Comparison: Stock Vs Aftermarket

The stock CB650R exhaust is quiet. It has a muted inline-four sound. Aftermarket exhausts change everything.

Stock exhaust: Muffled, quiet, no character. You can barely hear the engine at idle.

Slip-on exhaust: Louder, deeper, more aggressive. You hear the inline-four scream at high RPMs.

Full system: Very loud, raw, race-like. It can be too loud for some riders. Use a baffle to tone it down.

Sound is subjective. Some riders want loud. Others want refined. Listen to videos online before buying.

Weight Savings And Performance Gains

Weight savings vary by exhaust. Here are approximate numbers.

Stock system: 15-18 pounds.
Slip-on: Saves 3-5 pounds.
Full system: Saves 8-12 pounds.

Performance gains depend on the system and tuning. A slip-on adds 1-2 horsepower. A full system with tune adds 5-8 horsepower. You also get better throttle response.

Weight savings improve handling. The bike feels lighter and more nimble. It is a noticeable difference.

Cost Considerations For Exhaust Upgrades

Exhaust prices vary widely. Here is what you can expect.

Slip-on: $300 to $800.
Full system: $800 to $1500.
ECU tune: $200 to $500.

Budget for the exhaust plus tuning if needed. A slip-on is cheaper but offers less performance. A full system is an investment.

Do not forget installation costs if you cannot DIY. A shop might charge $100-$200. Factor that into your budget.

Legal And Noise Considerations

Loud exhausts can attract attention. Check local noise laws. Some areas have strict decibel limits.

Most aftermarket exhausts come with a removable baffle. Use it for street riding. Remove it for track days.

Some exhausts are not street legal. Look for EPA or DOT approval if needed. Akrapovic and Yoshimura offer legal options.

Maintenance Tips For Your New Exhaust

Keep your exhaust looking good. Clean it regularly. Use a mild cleaner and soft cloth.

Check bolts for tightness after the first few rides. Heat cycles can loosen them. Re-torque as needed.

If you have a titanium system, it will change color with heat. This is normal. Some riders like the blue and gold hues.

Carbon fiber parts need care. Avoid harsh chemicals. Use a protectant to prevent fading.
