A new exhaust for the Honda CBR650R can sharpen the bike’s mid-range character without becoming overwhelming. If you are searching for the Best Exhaust For Honda Cbr650r, you have come to the right place. This guide will walk you through the top options, what to look for, and how to pick the perfect system for your riding style.
The CBR650R is a fantastic middleweight sportbike, but the stock exhaust is heavy and quiet. Swapping it out can save weight, improve sound, and even add a few horsepower. Let’s get into the details.
Best Exhaust For Honda Cbr650r
When you start looking for the best exhaust for your Honda CBR650R, you will find many choices. The market is full of slip-ons and full systems. Each has its own pros and cons. Here is a breakdown of the top contenders.
Top Slip-On Exhaust Options
Slip-on exhausts are the easiest upgrade. They replace just the muffler, keeping the stock headers. This makes them cheaper and simpler to install. Here are the best slip-ons for the CBR650R.
- Akrapovic Slip-On Line (Carbon or Titanium): This is a popular choice. It gives a deeper, more refined sound without being too loud. It saves about 4-5 pounds compared to stock. The build quality is top-notch.
- Yoshimura Alpha T: Known for a aggressive, race-inspired tone. The Alpha T is a bit louder than the Akrapovic. It uses a titanium muffler and a carbon fiber end cap. It looks and sounds great.
- Two Brothers Racing M-5 Black Series: A more affordable option. It offers a good sound improvement and a sleek black finish. It is a bit heavier than carbon options but still lighter than stock.
- LeoVince LV-10: This is a short, stubby exhaust. It gives a very loud, raw sound. It is not for everyone, but if you want maximum noise, this is it. It saves a lot of weight too.
Full Exhaust Systems
Full systems replace the headers and the muffler. They offer the biggest performance gains. They are more expensive and harder to install. But they can add 5-8 horsepower and save up to 10 pounds.
- Akrapovic Full System (Titanium): The gold standard. It is light, sounds amazing, and adds real power. It requires a ECU flash or a fuel controller to run properly. It is the most expensive option.
- SC-Project CR-T Full System: A very aggressive, loud system. It is popular for track use. The sound is deep and throaty. It also needs tuning to work best.
- Arrow Pro-Race Full System: A good middle ground. It is not as loud as the SC-Project but still offers good power gains. It is made from stainless steel and titanium. It is a durable choice.
- Mivv MK3 Full System: A more budget-friendly full system. It gives a solid sound and power boost. It is heavier than titanium systems but still a big improvement over stock.
Key Factors To Consider
Before you buy, think about these things. They will help you choose the right exhaust for your needs.
Sound Level
Some exhausts are very loud. Others are more civilized. Think about where you ride. If you commute daily, a loud exhaust might annoy your neighbors. If you ride on the track, loud is fine.
Weight Savings
The stock exhaust is heavy. A slip-on can save 4-6 pounds. A full system can save 8-12 pounds. Less weight makes the bike feel more nimble. It is a noticeable difference.
Performance Gains
Slip-ons give minimal power gains, maybe 1-2 horsepower. Full systems can give 5-8 horsepower. But you need a tune to unlock that power. Without a tune, a full system might even lose power.
Installation Difficulty
Slip-ons are easy. You can do it in your garage with basic tools. Full systems are harder. You might need to remove the fairings and the radiator. It can take a few hours. If you are not handy, pay a shop.
Price
Slip-ons cost $300 to $800. Full systems cost $800 to $1500. Add another $300 to $500 for a ECU flash. Set a budget before you start shopping.
How To Install A Slip-On Exhaust
Installing a slip-on is straightforward. Here is a step-by-step guide. It should take about 30-60 minutes.
- Park the bike on a flat surface. Let it cool down completely.
- Loosen the clamp that connects the muffler to the header pipe. It is usually a bolt or a spring.
- Remove the bolt that holds the muffler to the passenger peg bracket. You might need a socket wrench.
- Slide the old muffler off the header pipe. It might be stuck. Wiggle it gently.
- Clean the header pipe where the new muffler will go. Use a rag and some degreaser.
- Slide the new slip-on onto the header pipe. Do not tighten it yet.
- Align the new muffler with the bracket. Install the new bolt and washer. Tighten it hand-tight.
- Adjust the muffler so it is straight and looks good. Then tighten the header clamp.
- Double-check all bolts and clamps. Start the bike. Listen for leaks. If you hear a hiss, tighten the clamp more.
How To Install A Full Exhaust System
This is more complex. It is best to have some mechanical experience. Here is a general overview. Always follow the instructions that come with your exhaust.
- Remove the fairings. You will need to take off the lower side panels and the belly pan.
- Disconnect the O2 sensor. It is located on the header pipe. Be careful not to damage it.
- Remove the stock header pipes. They are bolted to the engine. You might need to remove the radiator fan for clearance.
- Remove the stock muffler. It is held by a bolt and a clamp.
- Install the new header pipes. Use new gaskets at the cylinder head. Tighten the bolts to the correct torque.
- Install the new muffler. Connect it to the header pipe. Do not tighten anything yet.
- Reconnect the O2 sensor. You might need an extension wire.
- Align all parts. Make sure nothing touches the swingarm or the tire. Then tighten all bolts.
- Reinstall the fairings. Start the bike. Check for leaks and clearance issues.
- You will need a ECU flash or a fuel controller. The bike will run lean without it. This can cause overheating or engine damage.
Why You Need A Tune
Many people skip the tune. That is a mistake. A full exhaust changes the air-fuel ratio. The stock ECU cannot adjust enough. This makes the bike run lean. Lean means hot. Hot means less power and potential damage.
A ECU flash fixes this. It adjusts the fuel map for the new exhaust. It can also improve throttle response and smoothness. It is a necessary step for full systems. For slip-ons, a tune is optional but recommended for best results.
Popular tuning options include:
- BrenTuning ECU Flash: Mail-in service. Very popular. They have maps for most exhausts.
- Power Commander V: A fuel controller. You install it and load a map. It is easy to use.
- Woolich Racing Tuning: More advanced. You can adjust the tune yourself with a laptop.
Sound Comparison: Stock Vs. Aftermarket
The stock exhaust is very quiet. It sounds like a sewing machine. An aftermarket exhaust changes everything. Here is a rough comparison.
- Stock: Quiet, muffled, no character. You can barely hear it at highway speeds.
- Akrapovic Slip-On: Deep, bassy, refined. It is louder but not obnoxious. It sounds like a bigger bike.
- Yoshimura Alpha T: Aggressive, raspy, loud. It has a distinct race bike sound. It turns heads.
- SC-Project CR-T: Very loud, raw, almost obnoxious. It is for people who want maximum noise. Expect attention.
- Full System (any brand): Louder than slip-ons. More volume and a deeper tone. It sounds like a proper sportbike.
Legal Considerations
Aftermarket exhausts are often louder than legal limits. Check your local laws. Some places have strict noise regulations. You might get a ticket. Some exhausts come with removable baffles. You can insert them to reduce noise for inspections.
Also, some exhausts do not have a catalytic converter. This might fail an emissions test. Keep the stock exhaust for inspections if needed.
Maintenance Tips
Aftermarket exhausts need some care. Here are a few tips to keep it looking and sounding good.
- Clean it regularly. Use a mild cleaner and a soft cloth. Avoid harsh chemicals.
- Check the bolts and clamps. They can loosen over time. Tighten them if needed.
- Watch for discoloration. Titanium turns blue or gold with heat. That is normal. Stainless steel should stay silver.
- Do not use abrasive polishes. They can scratch the finish.
- If you ride in rain or salt, clean it more often. Corrosion can happen.
